GI-2 PRECAUTIONS • Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. Precautions for NATS V2.0 (For Gasoline Engine Model) NATS (Nissan Anti-Theft System) SGI916 NATS V2.0 will immobilize the engine if someone tries to start it without the registered key of NATS V2.0 Both of the
originally supplied ignition key IDs have been NATS registered. The NATS security indicator is located on the instrument panel. The indicator blinks when the ignition switch is in "OFF" or "ACC" position. Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system • When NATS detects trouble, the malfunction indicator lamp (MIL) blinks. This blinking indicates that the anti-theft is not functioning, so prompt service is required. • When servicing NATS (trouble diagnoses, system initialisation and additional registration of other NATS ignition key IDs), CONSULT hardware and CONSULT NATS software is necessary. Regarding the procedures of NATS initialisation and NATS ignition key 10 registration, refer to CONSULT operation manual, NATS V2.0 Therefore, CONSULT NATS software (program card and operation manual) must be kept strictly confidential to maintain the integrity of the anti-theft function. • When servicing NATS V2.0 (trouble
diagnoses, system initial isation and additional registration of other NATS ignition key IDs), it may be necessary to re-register original key identification. Therefore, be sure to receive all keys from vehicle owner. A maximum of four key IDs can be registered into NATS. • When failing to start the engine first-time using the key of NATS V2.0, start as follows (1) Turn ignition key to "OFF". (2) Wait approx. 5 seconds (3) Turn ignition key to "START" again while keeping the key apart from any others on key-chain. General Precautions • Do not operate the engine for an extended period of time without proper exhaust ventilation. Keep the work area well ventilated and free of any flammable materials. Special care should be taken when handling any flammable or poisonous materials, such as gasoline, refrigerant gas, etc. When working in a pit or other enclosed area, be sure to properly ventilate the area before working with hazardous materials. Do not smoke while
working on the vehicle. SGI285 GI-3 • PRECAUTIONS General Precautions (Contd) • • Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent the vehicle from moving. After jacking up the vehicle, support the vehicle weight with safety stands at the points designated for proper lifting before working on the vehicle. These operations should be done on a level surface. When removing a heavy component such as the engine or transaxle/transmission, be careful not to lose your balance and drop them. Also, do not allow them to strike adjacent parts, especially the brake tubes and master cylinder. • Before starting repairs which do not require battery power: Turn off ignition switch. Disconnect the negative battery terminal. • To prevent serious burns: Avoid contact with hot metal parts. Do not remove the radiator cap when the engine is hot. • Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate
covers. Take caution that keys, buckles or buttons do not scratch paint. • Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly. Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones Replace inner and outer races of tapered roller bearings and needle bearings as a set. Arrange the disassembled parts in accordance with their assembled locations and sequence. Do not touch the terminals of electrical components which use microcomputers (such as ECMs). Static electricity may damage internal electronic components. SEF289H SGI233 SGI234 • • • • GI-4 PRECAUTIONS General Precautions (Contd) • • • • • • After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection. Use only the fluids and lubricants specified in this manual. Use approved bonding agent, sealants or their equivalents when required. Use tools and recommended special
tools where specified for safe and efficient service repairs. When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks. Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner. Precautions for Multiport Fuel Injection System or ECCS Engine • • • Before connecting or disconnecting any harness connector for the multiport fuel injection system or EGM (EGGS control module): Turn ignition switch to "OFF" position. Disconnect negative battery terminal. Otherwise, there may be damage to EGM. Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure. Be careful not to jar components such as EGM and mass air flow sensor. Precautions for Three Way Catalyst If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To prevent this, follow the instructions below: • Use unleaded gasoline only. Leaded
gasoline will seriously damage the three way catalyst. • When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary. • Do not run engine when the fuel tank level is low, otherwise the engine may misfire causing damage to the catalyst. Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three way catalyst Engine Oils Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact with used oil If skin contact is .made, wash thoroughly with soap or hand cleaner as soon as possible. HEALTH PROTECTION • • • • PRECAUTIONS Avoid prolonged and repeated contact with oils, particularly used engine oils. Wear protective clothing, including impervious gloves where practicable. Do not put oily rags in pockets. Avoid contaminating clothes, particularly underpants, with oil. • • • Heavily soiled clothing and oil-impregnated footwear
should not be worn. Overalls must be cleaned regularly First Aid treatment should be obtained immediately for open cuts and wounds. Use barrier creams, applying them before each work period, to help the removal of oil from the skin. GI-5 • PRECAUTIONS Engine Oils (ConI d) • • • • • Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the natural skin oils which have been removed. Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or solvents for cleaning skin. If skin disorders develop, obtain medical advice without delay. Where practicable, degrease components prior to handling. Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face shields; in addition an eye wash facility should be provided. ENVIRONMENTAL PROTECTION PRECAUTIONS Burning used engine oil in small space heaters or boilers can be recommended only for
units of approved design. The heating system must meet the requirements of HM Inspectorate of Pollution for small burners of less than 0.4 MW If in doubt check with the appropriate local authority and/or manufacturer of the approved appliance. Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste disposal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal facilities. It is illegal to pour used oil on to the ground, down sewers or drains, or into water courses. The regulations concerning the pollution of the environment will vary between regions. Precautions GASOLINE for Fuel ENGINE: For Europe Unleaded gasoline of at least 95 octane (RON) CAUTION: Do not use leaded gasoline. Using leaded gasoline will damage the catalytic converter. Except Europe Unleaded gasoline of at least 91 octane (RON) DIESEL ENGINE*: Diesel fuel of at least 50 cetane If two types of diesel fuel
are available, use summer or winter fuel properly according to the following temperature conditions. • Above (20°F) Summer type diesel fuel. • Below (20°F) Winter type diesel fuel. CAUTION: • Do not use home heating oil, gasoline, or other alternate fuels in your diesel engine. The use of those can cause engine damage. • Do not use summer fuel at temperature below 7°C (20°F). The cold temperatures will cause wax to form in the fuel. As a result, it may prevent the engine from running smoothly. • Do not add gasoline or other alternate fuels to diesel fuel. -rc -rc GI-6 HOW TO USE THIS MANUAL • • • • • • ALPHABETICAL INDEX is provided at the end of this manual so that you can rapidly find the item and page you are searching for.

The following are key pieces of information required to make a good analysis: WHAT Vehicle Model, Engine, Transmission and the System (i.e Radio) WHEN Date, Time of Day, Weather Conditions, Frequency. WHERE Road Conditions, Altitude
and Traffic Situation. HOW System Symptoms, Operating Conditions (Other Components Interaction). Service History and if any After Market Accessories have been installed. STEP 2 Operate the system, road test if necessary. Verify the parameter of the incident. If the problem can not be duplicated, refer to "Incident Simulation Tests" next page. STEP 3 Get the proper diagnosis materials together including: POWER SUPPLY ROUTING System Operation Descriptions Applicable Service Manual Sections Identify where to begin diagnosis based upon your knowledge of the system operation and the customer comments. STEP 4 Inspect the system for mechanical binding, loose connectors or wiring damage. Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness Layouts. STEP 5 Repair or replace the incident circuit or component. STEP 6 Operate the system in all modes. Verify the system works properly under all conditions Make sure you
have not inadvertently created a new incident during your diagnosis or repair steps. GI-18 HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT Incident Simulation Tests INTRODUCTION Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis The following section illustrates ways to simulate the conditionslenvironment under which the owner experiences an electrical incident. The section is broken into the six following • Vehicle vibration • Heat sensitive • Freezing • Water intrusion • Electrical load • Cold or hot start up Get a thorough description tions of the problem. topics: of the incident from the customer. It is important for simulating the condi- VEHICLE VIBRATION The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with AIC on). In such a case, you
will want to check for a vibration related condition Refer to the illustration below. Connectors & harness Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently shake each connector and harness while monitoring the system for the incident you are trying to duplicate. This test may indicate a loose or poor electrical connection Hint Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector terminals. A visual inspection may not reveal this without disconnecting the connector If the problem occurs intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the terminals on related connectors in the system. Sensors & relays Gently apply a slight vibration to sensors and relays in the system you are inspecting. This test may indicate a loose or poorly mounted sensor or relay. Vibration test Tap gently. Bend gently. GI-19 8GI839

from the harness side of the connector. Most DMMs have accessory alligator clips Slide these over the probe to allow clipping the "T" pin for a better contact. If you have any difficulty probing a terminal, inspect the terminal. Ensure you have not accidentally opened the contact spring or pulled a wire loose. GI-20 HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT Incident Simulation Tests (Contd) Engine compartment There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the things to check for are: • • • • • Connectors not fully seated. Wiring harness not long enough and is being stressed to engine vibrations or rocking. Wires laying across brackets or moving components. Loose, dirty or corroded ground wires. Wires routed too close to hot components. due To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to GROUND INSPECTION described later) First
check that the system is properly grounded. Then check for loose connection by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the wiring for continuity. Behind the instrument panel An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehicle vibration can aggravate a harness which is routed along a bracket or near a screw. Under seating areas An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides) during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or pinching Heating HEAT SENSITIVE test The owners problem may occur during hot weather or after car has sat for a short time. In such cases you will want to check for a heat sensitive condition. To determine if an electrical component is heat sensitive, heat the component with a heat gun or equivalent. Do not heat components above 60°C
(140°F). If incident occurs while heating the unit, either replace or properly insulate the component. Do not heat above 60°C (140°F). 8GI842 GI-21 • HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT Incident Simulation Tests (Contd) FREEZING Freezing test Water in connector Solenoid SGI843 The customer may indicate the incident goes away after the car warms up (winter time). The cause could be related to water freezing somewhere in the wiring/electrical system. There are two methods to check for this. The first is to arrange for the owner to leave his car overnight. Make sure it will get cold enough to demonstrate his complaint. Leave the car parked outside overnight. In the morning, do a quick and thorough diagnosis of those electrical components which could be affected. The second method is to put the suspect component into a freezer long enough for any water to freeze. Reinstall the part into the car and check for the reoccurrence of the incident. If it
occurs, repair or replace the component. WATER INTRUSION Water Intrusion test The incident may occur only during high humidity or in rainy/ snowy weather. In such cases the incident could be caused by water intrusion on an electrical part. This can be simulated by soaking the car or running it through a car wash. Do not spray water directly on any electrical components. SGI844 ELECTRICAL Electrical load test LOAD The incident may be electrical load sensitive. Perform diagnosis with all accessories (including A/C, rear window defogger, radio, fog lamps) turned on. COLD OR HOT START UP AIC On some occasions an electrical incident may occur only when the car is started cold. Or it may occur when the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to make a proper diagnosis. SGI845 GI-22 HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT Circuit Inspection INTRODUCTION In general, testing electrical
circuits is an easy task if it is approached in a logical and organized method. Before beginning it is important to have all available information on the system to be tested. Also, get a thorough understanding of system operation. Then you will be able to use the appropriate equipment and follow the correct test procedure. You may have to simulate vehicle vibrations while testing electrical components. Gently shake the wiring harness or electrical component to do this OPEN A circuit SHORT There are two types of shorts. is open when there is no continuity through a section of the circuit. • SHORT CIRCUIT When a circuit contacts another circuit and causes the normal resistance to change. • SHORT TO GROUND When a circuit contacts a ground source and grounds the circuit. TESTING FOR "OPENS" IN THE CIRCUIT Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This will help you to logically walk through the diagnosis
process. Drawing the sketch will also reinforce your working knowledge of the system. Inspection for opens [YJ - (Voltage check) + DMM Ll I I B + SIDE I L ~SE. ~L9~K I -,---- OPEN A I I -.J [ill DMM SGI846 Continuity check method The continuity check is used to find an open in the circuit. The Digital Multimeter (DMM) set on the resistance function will indicate an open circuit as over limit (OL, no beep tone or no ohms symbol). Make sure to always start with the DMM at the highest resistance level. To help in understanding the diagnosis of open circuits please refer to the schematic above. 1. 2. Disconnect the battery negative cable. Start at one end of the circuit and work your way to the.other end (At the fuse block in this example) 3. Connect one probe of the DMM to the fuse block terminal on the load side 4. Connect the other probe to the fuse block (power) side of SW1 Little or no resistance will indicate that portion of the circuit has good continuity. If there
were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point A) 5. Connect the probes between SW1 and the relay Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point B) 6. Connect the probes between the relay and the solenoid Little or no resistance will indicate that portion of the circuit has good continuity If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point C) Any circuit can be diagnosed using the approach in the above example. GI-23 • HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT Circuit Inspection (Contd) Voltage check method To help in understanding the diagnosis of open circuits please refer to the previous schematic. In any powered circuit, an open can be found by methodically checking the system
for the presence of voltage. This is done by switching the DMM to the voltage function 1. Connect one probe of the DMM to a known good ground 2. Begin probing at one end of the circuit and work your way to the other end 3. With SW1 open, probe at SW1 to check for voltage voltage; open is further down the circuit than SW1. no voltage; open is between fuse block and SW1 (point A). 4. Close SW1 and probe at relay voltage; open is further down the circuit than the relay. no voltage; open is between SW1 and relay (point B). 5. Close the relay and probe at the solenoid voltage; open is further down the circuit than the solenoid. no voltage; open is between relay and solenoid (point C). Any powered circuit can be diagnosed using the approach in the above example. TESTING FOR "SHORTS" To simplify the discussion IN THE CIRCUIT of shorts in the system please refer to the schematic below. Inspection for shorts t (Resistance check) IGN "ON" OR "S~:R.T~ RELAY

Remove the blown fuse and disconnect all loads (i.e SW1 open, relay disconnected and solenoid disconnected) powered through the fuse. Turn the ignition key to the ON or START position. Verify battery voltage at the B + side of the fuse terminal (one lead on the B + terminal side of the fuse block and one lead on a known good ground). With SW1 open and the DMM leads across both fuse terminals, check for voltage. voltage; short is between fuse block and SW1 (point A). no voltage; short is further down the circuit than SW1. With SW1 closed, relay and solenoid disconnected and the DMM leads across both fuse terminals, check for voltage. voltage; short is between SW1 and the relay (point B). no voltage; short is

With SW1 closed, relay contacts jumped with fused jumper wire check for voltage. voltage; short is down the circuit of the relay or between the relay and the disconnected solenoid (point C). no voltage; retrace steps and check power to fuse block. GROUND INSPECTION Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwanted resistance. This unwanted resistance can change the way a circuit works. Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit Even when the ground connection looks clean, there can be a thin film of rust on the surface When inspecting a ground connection follow these rules: 1. Remove the ground
bolt screw or clip 2. Inspect all mating surfaces for tarnish, dirt, rust, etc 3. Clean as required to assure good contact 4. Reinstall bolt or screw securely 5. Inspect for "add-on" accessories which may be interfering with the ground circuit 6. If several wires are crimped into one ground eyelet terminal, check for proper crimps Make sure all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one eyelet make sure no ground wires have excess wire insulation. Ground Inspection • • Remove boll (screw). • Inspect mating surfaces for tarnish. dirt rust etc Clean as required to assure good contact. Reinstall bolt (screw) securely. SGI853 GI-25 • HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT Circuit Inspection (Contd) VOLTAGE DROP TESTS Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage drop in a circuit is caused by a resistance when
the circuit is in operation. Check the wire in the illustration. When measuring resistance with ohmmeter, contact by a single strand of wire will give reading of 0 ohms. This would indicate a good circuit When the circuit operates, this single strand of wire is not able to carry the current. The single strand will have a high resistance to the current. This will be picked up as a slight voltage drop Unwanted resistance can be caused by many situations as follows: Undersized wiring (single strand example) Corrosion on switch contacts Loose wire connections or splices. If repairs are needed always use wire that is of the same or larger gauge. Measuring 1. 2. 3. voltage drop - Accumulated method Connect the voltmeter across the connector or part of the circuit you want to check. The positive lead of the voltmeter should be closer to power and the negative lead closer to ground. Operate the circuit. The voltmeter will indicate how many volts are being used to "push" current
through that part of the circuit. Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb Symptom: Dim bulb or no operation o (zero) ohm resistance between switch and bulb ------------------~ -- I OV I ~~~~ DMM -, 12V 11.9V: I I -- Load) Switch -- Ground Connection with high resistance l ; Battery t • Ground SGI848 Measuring voltage drop - Step by step The step by step method is most useful for isolating excessive those in "Computer Controlled Systems"). Circuits in the "Computer Controlled System" operate on very The (Computer Controlled) system operations can be adversely in the system. Such resistance variation may be caused by improper wire gauge or corrosion. The step by step voltage drop test can identify a component or GI-26 drops in low voltage systems (such as low amperage. affected by any variation in resistance poor connection, improper installation, wire with too much
resistance. HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT Circuit Inspection (Contd) 1. Connect the voltmeter as shown, starting at the battery and working your way around the circuit. 2. An unusually large voltage drop will indicate a component or wire that needs to be repaired. As you can see the illustration above, the poor connection causes a 4 volt drop. The chart that follows illustrates some maximum allowable voltage drops. These values are given as a guideline, the exact value for each component may vary.

Speed: Below 50 km/h (30 MPH) Distance: Less than 65 km (40 miles) CAUTION: Never tow an automatic transaxle model from the rear (i.e, backward) with four wheels on the ground as this may cause serious and expensive damage to the transaxle. TOWING AN AUTOMATIC TRANSAXLE MODEL WITH
REAR WHEELS RAISED (With front wheels on ground) Never tow an automatic transaxle model with rear wheels raised (with front wheels on ground) as this may cause serious and expensive damage to the transaxle. If it is necessary to tow it with rear wheels raised, always use a towing dolly under the front wheels. SG1806-A TOWING POINT Always pull the cable straight out from the vehicle. Never pull on the hook at a sideways angle. CAUTION: Remove the front spoiler when towing the vehicle forward. Otherwise, the towing device may damage the front spoiler.

They are essential if the vehicle is to continue operating properly The owners can perform the checks and inspections themselves or they can have their NISSAN dealers do them. Reference pages Item OUTSIDE THE VEHICLE The maintenance items listed here should be performed from time to time, unless otherwise specified. Tires Check the pressure with a gauge periodically when at a service station, including the spare, and adjust to the specified pressure if necessary. Check carefully for damage, cuts or excessive wear. Windshield wiper blades Check for cracks or wear if they do not wipe properly. Doors and engine hood Check that all doors, the engine hood,
the trunk lid and back door operate properly. Also ensure that all latches lock securely Lubricate hinges, latches, rollers and links if necessary. Make sure that the secondary latch keeps the hood from opening when the primary latch is released. When driving in areas using road salt or other corrosive materials, check for lubrication frequently. Tire rotation Tires should be rotated every 10,000 km (6,000 miles). MA-51 MA-50 INSIDE THE VEHICLE The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the vehicle, etc. Lights Make sure that the headlights, stop lights, tail lights, turn signal lights, and other lights are all operating properly and installed securely. Also check headlight aim Warning lights and buzzers/chimes Make sure that all warning lights and buzzers/chimes are operating properly. Steering wheel Check for change in the steering conditions, such as excessive free play, hard steering or strange
noises. Free play: Less than 35 mm (1.38 in) Seat belts Check that all parts of the seat belt system (e.g buckles, anchors, adjusters and retractors) operate properly and smoothly, and are installed securely. Check the belt webbing for cuts, fraying, wear or damage. UNDER THE HOOD AND VEHICLE The maintenance items listed here should be checked periodically e.g each time you check the engine oil or refuel. Windshield washer fluid Check that there is adequate fluid in the tank. Engine coolant level Check the coolant level when the engine is cold. MA-19,38 Engine oil level Check the level after parking the vehicle on a level spot and turning off the engine. MA-24, 33, 41 Brake and clutch fluid levels Make sure that the brake and clutch fluid levels are between the "MAX" and "MIN" lines on the reservoir. MA-45,47 Battery Check the fluid level in each cell. It should be between the "MAX" and "MIN" lines. MA-6 PERIODIC MAINTENANCE (Except

If compression in one or more cylinders is low: a. Pour a small amount of engine oil into cylinders through spark plug holes. b. Re-test compression, • If adding oil helps compression, piston rings may be worn or damaged. If so, replace piston rings after checking piston • If pressure stays low, a valve may be sticking or seating improperly. Inspect and repair valve and valve seat Refer to SOS (EM-156, 159). If valve or valve seat is damaged excessively, replace them. • If compression stays low in two cylinder that are next to each other: The cylinder head gasket may be leaking, or both cylinders may have valve component damage.

EC-7 risk of personal injury or death maintenance must be performed of the SRS, can lead to personal SRS unless instructed to in this PRECAUTIONS AND PREPARATION I GA, SR Engine Fuel & Emission Control System ECM • Do not disassembly module). EGM (EGGS control • Do not turn diagnosis forcibly. BATTERY •
Always use a 12 volt battery as power source. mode selector • If a battery terminal is disconnected, the memory will return to the ECM value. The ECM will now start to self-control at its initial value. Engine operation can vary slightly when the terminal is disconnected. However, this is not an indication of a problem. Do not replace parts because of a slight variation. • Do not attempt to disconnect battery cables while engine is running. WIRELESS EQUIPMENT • When installing C.B ham radio or a mobile phone, be sure to observe the following as it may adversely affect electronic control systems depending on its installation location . 1) Keep the antenna as far as possible away from the EGM. 2) Keep the antenna feeder line more than 20 em (7.9 in) away from the harness of electronic controls. Do not let them run parallel for a long distance. 3) Adjust the antenna and feeder line so that the standing-wave ratio can be kept smaller. 4) Be sure to ground the radio to vehicle
body. INJECTOR • Do not disconnect injector harness connectors with engine running . • Do not apply battery injectors. power directly to ECCS PARTS HANDLING • Handle mass air flow sensor carefully avoid damage. • Do not disassemble mass air flow sensor. to • Do not clean mass air flow sensor with any type of detergent. • Do not disassemble • Even a system • Do not position IACV-AAC valve. slight leak in the air intake can cause serious problems. shock or jar the camshaft sensor. WHEN STARTING • Do not depress accelerator starting. pedal when • Immediately after starting, do not rev up engine unnecessarily . • Do not rev up engine just prior to shutdown. FUEL PUMP • Do not operate fuel pump when there is no fuel in lines. • Tighten fuel hose clamps to the specified torque. ECCS HARNESS HANDLING • Securely connect EGGS harness connectors. A poor connection can cause an extremely high (surge) voltage to develop in coil and condenser, thus resulting
in damage to ICs . • Keep ECGS harness at least 10 em (3.9 in) away from adjacent harnesses, to prevent an EGGS system malfunction due to receiving external noise, degraded operation of IGs, etc . • Keep EGCS parts and harnesses dry . • Before removing parts, turn off ignition switch and then disconnect battery ground cable. SEF320R EC-8 I PRECAUTIONS AND PREPARATION I GA, SR I Precautions for ECCS Trouble Diagnosis of Engine CAUTION: • Be sure to turn the ignition switch "OFF" and disconnect the negative battery terminal before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc will cause malfunction. • Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will cause malfunction due to the open circuit. (Be sure the connector is free from water, grease, dirt, bent terminals, etc.) • Be sure to route and clamp the harnesses properly after work. The interference of
the harness with a bracket, etc. may cause malfunction due to the short circuit • Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube • may cause malfunction. • Be sure to erase the unnecessary malfunction information (repairs completed) in the ECM before returning the vehicle to the customer. Precautions • Before connecting or disconnecting the ECM harness connector, turn ignition switch OFF and disconnect negative battery terminal. Failure to do so may damage the ECM because battery voltage is applied to ECM even if ignition switch is turned off. • When connecting ECM harness connector, tighten securing bolt until red projection is in line with connector face. • When connecting or disconnecting pin connectors into or from ECM, take care not to damage pin terminals (bend or break). Make sure that there are not any bends or breaks on ECM pin terminal, when connecting pin connectors. SEF289H SEF725H Bend Break SEF291H
EC-9 PRECAUTIONS AND PREPARATION Precautions (Contd) " / - ~/" / • Before replacing ECM, perform Terminals and Reference Value inspection and make sure ECM functions properly. Refer to EC-281 for SR engine model and EC-78 for GA engine model. • After performing each TROUBLE DIAGNOSIS, perform "OVERALL FUNCTIONCHECK" or "DTC (Diagnostic Trouble Code) CONFIRMATIONPROCEDURE". The DTC should not be displayed in the "DTC CONFIRMATION PROCEDURE"if the repair is completed. The "OVERALL FUNCTION CHECK" should be a good result if the repair is completed. • When measuring ECM signals with a circuit tester, never allow the two tester probes to contact. Accidental contact of probes will cause a short circuit and damage the ECM power transistor. MEF040D I / CHECK- / , I GA, SR I .

The ECM controls the length of time the valve remains open (injection pulse duration). The amount of fuel injected is a program value in the ECM memory. The program value is preset by engine operating conditions. These conditions are determined by input signals (for engine speed and intake air) from both the camshaft position sensor and the mass air flow sensor. In addition, the amount of fuel injected is compensated to improve engine performance under various operating conditions as listed below. < Fuel increase> • During warm-up • When starting the engine • During acceleration • Hot-engine operation • When
selector lever is changed from "N" to "D" (AfT models only) • High-load, high-speed operation < Fuel decrease> • During deceleration EC-24 ENGINE AND EMISSION BASIC CONTROL SYSTEM DESCRIPTION [ill Multipart Fuel Injection (MFI) System (Cant d) MIXTURE RATIO FEEDBACK CONTROL (CLOSED LOOP CONTROL) CLOSED LOOP CONTROL Feedback signal MEF025DC The mixture ratio feedback system provides the best air-fuel mixture ratio for driveability and emission control. The three way catalyst can then better reduce CO, HC and NOx emissions. This system uses an oxygen sensor*1 in the exhaust manifold to monitor if the engine operation is rich or lean. The ECM adjusts the injection pulse width according to the sensor voltage signal. This maintains the mixture ratio within the range of stoichiometric (ideal air-fuel mixture). This stage is referred to as the closed loop control condition . OPEN LOOP CONTROL The open loop system condition refers to when the ECM detects
any of the following conditions. Feedback control stops in order to maintain stabilized fuel combustion. • Deceleration and acceleration • High-load, high-speed operation • Engine idling • Malfunction of oxygen sensor*1 or its circuit • Insufficient activation of oxygen sensor*1 at low engine coolant temperature • High-engine coolant temperature • After shifting from "N" to "D" • During warm-up • When starting the engine MIXTURE RATIO SELF-LEARNING CONTROL The mixture ratio feedback control system monitors the mixture ratio signal transmitted from the oxygen sensor*1. This feedback signal is then sent to the ECM The ECM controls the basic mixture ratio as close to the theoretical mixture ratio as possible. However, the basic mixture ratio is not necessarily controlled as originally designed Both manufacturing differences (i.e, mass air flow sensor hot film) and characteristic changes during operation (i.e, injector clogging) directly affect
mixture ratio. Accordingly, the difference between the basic and theoretical mixture ratios is monitored in this system. This is then computed in terms of "injection pulse duration" to automatically compensate for the difference between the two ratios. * 1: Heated oxygen sensor (For Europe and Israel, and Australia AIT models) Oxygen sensor (Except for Europe and Israel, and Australia AIT models) EC-25 • ENGINE AND EMISSION BASIC CONTROL SYSTEM DESCRIPTION @K] Multipart Fuel Injection (MFI) System (Contd) No.1 cylinder ---r:T / Injection pUlse No.2 cylinder rL No.3 cylinder n. n.

Fuel filler cap with vacuum relief valve : Air Q : Fuel vapor EVAP canister SEF126R The evaporative emission system is used to reduce hydrocarbons emitted into
the atmosphere from the fuel system. This reduction of hydrocarbons is accomplished by activated charcoals in the EVAP canister. The fuel vapor from sealed fuel tank is led into the EVAP canister when the engine is off. The fuel vapor is then stored in the EVAP canister. The EVAP canister retains the fuel vapor until the EVAP canister is purged by air. When the engine is running, the air is drawn through the bottom of the EVAP canister. The fuel vapor will then be led to the intake manifold. When the engine runs at idle, the EVAP canister purge control valve is closed. Only a small amount of vapor flows into the intake manifold through the constant purge orifice. As the engine speed increases and the throttle vacuum rises, the purge control valve opens. The vapor is sucked through both main purge and constant purge orifices. Inspection EVAP CANISTER Check EVAP canister as follows: 1. Blow air in port @ and ensure that there is no leakage 2. Apply vacuum to port @ [Approximately -133
to -200 kPa (-133 to -200 mbar, -100 to -150 mmHg, -3.94 to -591 inHg)] 3. Cover port CID with hand 4.

If valve is clogged or if no resistance is felt, replace cap as an assembly. ~V""B Valve A Fuel tank side SEF427N EC-30 POSITIVE CRANKCASE VENTILATION Description This system returns blow-by gas to the intake manifold collector. The positive crankcase ventilation (peV) valve is provided to conduct crankcase blow-by gas to the intake manifold. During partial throttle operation of the engine, the intake manifold sucks the blow-by gas through the pev valve. Normally, the capacity of the valve is sufficient to handle any blow-by and a small amount of ventilating air. The ventilating air is then drawn from the air duct into the crankcase. In this process the air passes through the hose connecting air inlet tubes to rocker cover. Under full-throttle condition, the manifold vacuum is insufficient to draw the blow-by flow through the valve. The flow
goes through the hose connection in the reverse direction On vehicles with an excessively high blow-by, the valve does not meet the requirement. This is because some of the flow will go through the hose connection to the intake manifold collector under all conditions.

"AUTO TRIG" (Automatic trigger): • The malfunction will be identified on the CONSULT screen in real time. In other words, DTC and malfunction item will be displayed at the moment the malfunction is detected by ECM. DATA MONITOR can be performed continuously until a malfunction is detected. However, DATA MONITOR cannot continue any longer after the malfunction detection. 2. "MANU TRIG" (Manual trigger): • DTC and malfunction item will not be displayed automatically on CONSULT screen even though a malfunction is detected by ECM. • DATA MONITOR can be performed continuously even
though a malfunction is detected. Use these triggers as follows: 1. "AUTO TRIG" • While trying to detect the DTC by performing the "DTC CONFIRMATION PROCEDURE", be sure to select to "DATA MONITOR (AUTO TRIG)" mode. You can confirm the malfunction at the moment it is detected. • While narrowing down the possible causes, CONSULT should be set in "DATA MONITOR (AUTO TRIG)" mode, especially in case the incident is intermittent. Inspect the circuit by gently shaking (or twisting) suspicious connectors, components and harness in the "DTC CONFIRMATION PROCEDURE". The moment a malfunction is found the DTC will be displayed. (Refer to GI section, "Incident Simulation Tests" in "HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT".) 2. "MANU TRIG" • If the malfunction is displayed as soon as "DATA MONITOR" is selected, reset CONSULT to "MANU TRIG". By selecting "MANU
TRIG" you can monitor and store the data The data can be utilized for further diagnosis, such as a comparison with the value for the normal operating condition.

SEF674Q EC-57 TROUBLE DIAGNOSIS - General Description Introduction Sensors ~ ECM Actuators ~~.~ MEF036D The engine has an ECM to control major systems such as fuel control, ignition control, idle air control system, etc. The ECM accepts input signals from sensors and instantly drives actuators. It is essential that both input and output
signals are proper and stable. At the same time, it is important that there are no problems such as vacuum leaks, fouled spark plugs, or other problems with the engine. It is much more difficult to diagnose a problem that occurs intermittently rather than continuously. Most intermittent problems are caused by poor electric connections or improper wiring In this case, careful checking of suspected circuits may help prevent the replacement of good parts. A visual check only may not find the cause of the problems. A road test with CONSULTor a circuit tester connected should be performed. Follow the "Work Flow" on the next page Before undertaking actual checks, take just a few minutes to talk with a customer who approaches with a driveability complaint. The customer can supply good information about such problems, especially intermittent ones. Find out what symptoms are present and under what conditions they occur. A "Diagnostic Worksheet" like the example on EC-61
should be used Start your diagnosis by looking for "conventional" problems first. This will help troubleshoot driveability problems on an electronically controlled engine vehicle.

EC-59 • TROUBLE DIAGNOSIS - General oescrip ti on I G A Description for Work Flow STEP STEP I DESCRIPTION Get detailed information about the conditions and the environment when the incident/symptom occurred using the "DIAGNOSTIC WORKSHEET" as shown on the next page. STEP II Before confirming the concern, check and write down (print out using CONSULT) the Diagnostic Trouble Code (DTC), then erase the code. The DTC can be used when
duplicating the incident at STEP III & IV Study the relationship between the cause, specified by DTC, and the symptom described by the customer. (The "Symptom Matrix Chart" will be useful. Refer to EC-72) STEP III Try to confirm the symptom and under what conditions the incident occurs. The "DIAGNOSTIC WORK SHEET" is useful to verify the incident. Connect CONSULT to the vehicle in DATA MONITOR (AUTO TRIG) mode and check real time diagnosis results. If the incident cannot be verified, perform INCIDENT SIMULATION TESTS. Refer to GI section If the malfunction code is detected, skip STEP IV and perform STEP V. STEP IV Try to detect the Diagnostic Trouble Code (DTC) by driving in (or performing) the "DTC CONFIRMATION PROCEDURE". Check and read the DTC by using CONSULT During the DTC verification, be sure to connect CONSULT to the vehicle in DATA MONITOR (AUTO TRIG) mode and check real time diagnosis results. If the incident cannot be verified, perform
INCIDENT SIMULATION TESTS. Refer to GI section In case the "DTC CONFIRMATION PROCEDURE" is not available, perform the "OVERALL FUNCTION CHECK" instead. The DTC cannot be displayed by this check, however, this simplified "check" is an effective alternative The "NG" result of the "OVERALL FUNCTION CHECK" is the same as the DTC detection. STEP V Take the appropriate action based on the results of STEP I through IV. If the malfunction code is indicated, proceed to TROUBLE DIAGNOSIS FOR DTC XX. If the normal code is indicated, proceed to the BASIC INSPECTION. Refer to EC-65 Then perform inspections according to the Symptom Matrix Chart Refer to EC-72 Identify where to begin diagnosis based on the relationship study between symptom and possible causes. Inspect the system for mechanical binding, loose connectors or wiring damage using (tracing) "Harness STEP VI STEP VII Layouts". Gently shake the related connectors, components
or wiring harness with CONSULT set in "DATA MONITOR (AUTO TRIG)" mode. Check the voltage of the related ECM terminals or monitor the output data from the related sensors with CONSULT. Refer to EC-74 The "DIAGNOSTIC PROCEDURE" in EC section contains a description based on open circuit inspection. A short circuit inspection is also required for the circuit check in the DIAGNOSTIC PROCEDURE. For details, refer to GI section ("HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT", "Circuit Inspection ). Repair or replace the malfunction parts. Once you have repaired the circuit or replaced a component, you need to run the engine in the same conditions and circumstances which resulted in the customers initial complaint. Perform the "DTC CONFIRMATION PROCEDURE" and confirm the normal code (Diagnostic trouble code No. 55) is detected. If the incident is still detected in the final check, perform STEP VI by using a different method from the
previous one. Before returning the vehicle to the customer, be sure to erase the unnecessary (already fixed) DTC in ECM. Refer to EC-46.

It monitors engine speed and piston position These input signals to the EGM are used to control fuel injection, ignition timing and other functions. The camshaft position sensor has a rotor plate and a waveforming circuit. The rotor plate has 360 slits for a 1 (paS) signal (except for Europe and Israel) and 4 slits for a 180 (REF) signal. The wave-forming circuit consists of Light Emitting Diodes (LED) and photo diodes. The rotor plate is positioned between the LED and the photo diode. The LED transmits light to the photo diode As the rotor plate turns, the slits cut the light to generate rough-shaped pulses. These pulses are converted into on-off signals by the wave-forming
circuit and sent to the EGM. Light emitting diode 0 0 Wave formingcircuit SEF653B 1800 signal Diagnostic Trouble Code Malfunction is detected when .

SEF887K EC-100 TROUBLE DIAGNOSIS FOR DTC 12 Mass Air Flow Sensor (MAFS) SEF154N The mass air flow sensor measures the intake air flow rate by taking a part of the entire flow. Measurements are made in such a manner that the ECM receives electrical output signals varied by the amount of heat emitting from the hot wire placed in the stream of the intake air. When intake air flows into the intake manifold through a route around the hot wire, the heat generated from the hot wire is taken away by the air. The amount of heat depends on the air flow. On the other
hand, the temperature of the .hot wire is automatically controlled to a certain number of degrees. Therefore, it is necessary to supply the hot wire with more • electric current in order to maintain the temperature of the hot wire. The ECM knows the air flow by means of the electric c~ange. SEF695K Diagnostic Trouble Code No. 12 Check Items Malfunction is detected when . (Possible Cause) • An excessively high or low voltage from the sensor • Harness or connectors is entered to ECM.

HEC071 EC-142 TROUBLE DIAGNOSIS FOR NON-DETECTABLE Injector (Contd) COMPONENT ITEMS DESCRIPTION The fuel injector is a small, precise solenoid valve. When the ECM supplies a ground to the injector circuit, the coil in the injector is energized. The energized coil pulls the needle valve back and allows fuel to flow through the injector into the intake manifold. The amount of fuel injected depends upon the injection pulse duration Pulse duration is the length of time the injector remains open. The ECM controls the injection pulse duration based on engine fuel needs. SEF596K • ACTIVE TEST.

AEC559 EC-144 TROUBLE DIAGNOSIS FOR NON-DETECTABLE ITEMS Fuel Pump SYSTEM DESCRIPTION Engine speed Camshaft position sensor ECM (ECCS control module) Start signal Ignition switch The ECM activates the fuel pump for several seconds after the ignition switch is turned on to improve engine startability. If the ECM receives a 180 signal from the camshaft position sensor, it knows that the engine is rotating, and causes the pump to perform. If the 180 signal is not received when the ignition switch is on, the engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump. 0 Condition Ignition switch is turned to ON. Engine running and cranking Fuel pump relay Fuel pump operation Operates for 5 seconds Operates 0 When engine is stopped Stops in 1 second Except as shown above

IACV-AAC valve I Power steering load signal Power steering oil pressure switch I Battery Park/Neutral position ~ Battery voltage Vehicle speed Cooling fan operation Electrical load Blower fan operation : Rear window defogger switch and headlamp switch. This system automatically controls engine idle speed to a specified level. Idle speed is controlled through fine adjustment of the amount of air which bypasses the throttle valve via IACV-AAC valve. The IACV-AAC valve opens and closes (except for Europe and Israel), or repeats ON/OFF operation (for Europe and Israel), according to the signal sent from the ECM. The camshaft position sensor detects the actual engine speed and sends a signal to the ECM. The ECM then controls the IACV-AAC valve so that engine speed coincides with the target value
memorized in ECM. The target engine speed is the lowest speed at which the engine can operate steadily. The optimum value stored in the ECM is determined by taking into consideration various engine conditions, such as during warm up, deceleration, and engine load (air conditioner, power steering and cooling fan operation). COMPONENT DESCRIPTION IACV-AAC valve - Except for Europe and Israel The IACV-AAC valve is moved by open and close signals from the ECM. When the open signal is sent to the valve, the amount of air that will flow through the valve increases. The more air that flows through the valve, the higher the idle speed. When the close signal is sent to the valve. the amount of air decreases.

The ECM controls the length of time the valve remains open
(injection pulse duration). The amount of fuel injected is a program value in the ECM memory. The program value is preset by engine operating conditions. These conditions are determined by input signals (for engine speed and intake air) from both the camshaft position sensor and the mass air flow sensor. In addition, the amount of fuel injected is compensated to improve engine performance under various operating conditions as listed below. < Fuel increase> • During warm-up • When starting the engine • During acceleration • Hot-engine operation • When selector lever is changed from "N" to "0" (AfT models only) • High-load operation < Fuel decrease> • During deceleration EC-233 ENGINE AND EMISSION BASIC CONTROL SYSTEM DESCRIPTION [][] Multiport Fuel Injection (MFI) System (Contd) MIXTURE RATIO FEEDBACK CONTROL (CLOSED LOOP CONTROL) CLOSED LOOP CONTROL Feedback signal MEF025DD The mixture ratio feedback system provides the best
air-fuel mixture ratio for driveability and emission control. The three way catalyst can then better reduce CO, HC and NOx emissions. This system uses a heated oxygen sensor in the exhaust manifold to monitor if the engine operation is rich or lean. The ECM adjusts the injection pulse width according to the sensor voltage signal. For more information about the heated oxygen sensor, refer to EC-362. This maintains the mixture ratio within the range of stoichiometric (ideal air-fuel mixture). This stage is referred to as the closed loop control condition. OPEN LOOP CONTROL The open loop system condition refers to when the ECM detects any of the following conditions. Feedback control stops in order to maintain stabilized fuel combustion. • Deceleration and acceleration • High-load, high-speed operation • Engine idling • Malfunction of heated oxygen sensor or its circuit • Insufficient activation of heated oxygen sensor at low engine coolant temperature • High-engine coolant
temperature • After shifting from "N" to "0" • During warm-up • When starting the engine MIXTURE RATIO SELF-LEARNING CONTROL The mixture ratio feedback control system monitors the mixture ratio signal transmitted from the heated oxygen sensor. This feedback signal is then sent to the ECM. The ECM controls the basic mixture ratio as close to the theoretical mixture ratio as possible. However, the basic mixture ratio is not necessarily controlled as originally designed Both manufacturing differences (Le., mass air flow sensor hot wire) and characteristic changes during operation (Le., injector clogging) directly affect mixture ratio. Accordingly, the difference between the basic and theoretical mixture ratios is monitored in this system. This is then computed in terms of "injection pulse duration" to automatically compensate for the difference between the two ratios.

the ECM to maintain the best air-fuel ratio for every running condition of the engine. The ignition timing data is stored in the ECM. This data forms the map shown. The ECM receives information such as the injection pulse width and camshaft position sensor signal. Computing this information, ignition signals are transmitted to the power transistor. e.g, N: 1,800 rpm, Tp: 1.50 msec AOBTDC During the following conditions, the ignition timing is revised by the ECM according to the other data stored in the ECM. • At starting • During warm-up • At idle • Hot engine operation • During acceleration The knock sensor retard system is designed only for emergencies. The basic ignition timing is programmed within the antiknocking zone, if recommended fuel is used under dry conditions The retard system does not operate under normal driving conditions If engine knocking occurs, the knock sensor monitors the condition.

Camshaft position sensor Engine speed If the engine speed is above 3,950 rpm with no load (for example, in neutral and engine speed over 3,950 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies based on engine speed. Fuel cut will operate until the engine speed reaches 1,150 rpm, then fuel cut is cancelled. NOTE: This function is different than deceleration control listed under "Multipart Fuel Injection (MFI) System" on EC-233. EC-237 • EVAPORATIVE EMISSION SYSTEM Description EGR valve & EVAP canister purge control solenoid valve - Vapor vent line t - Fuel filler cap with vacuum relief valve Fuel tank EVAP canister yAir . Fuel vapor MEF609DC The evaporative emission system is used to reduce hydrocarbons emitted into the atmosphere from the fuel system. This reduction
of hydrocarbons is accomplished by activated charcoals in the EVAP canister. The fuel vapor from sealed fuel tank is led into the EVAP canister when the engine is off. The fuel vapor is then stored in the EVAP canister. The EVAP canister retains the fuel vapor until the EVAP canister is purged by air. When the engine is running, the air is drawn through the bottom of the EVAP canister. The fuel vapor will then be led to the intake manifold. When the engine runs at idle, the purge control valve is closed. Only a small amount of vapor flows into the intake manifold through the constant purge orifice. As the engine speed increases and the throttle vacuum rises, the purge control valve opens. The vapor is sucked through both main purge and .constant purge orifices Inspection EVAP CANISTER Check EVAP canister as follows: 1. Blow air in port @ and ensure that there is no leakage 2. • Apply vacuum to port @. [Approximately -133 to -200 kPa (-133 to -200 mbar, -100 to -150 mmHg, -3.94 to

The positive crankcase ventilation (PCV) valve is provided to conduct crankcase blow-by gas to the intake manifold. During partial throttle operation of the engine, the intake manifold sucks the blow-by gas through the pev valve. Normally, the capacity of the valve is sufficient to handle any blow-by and a small amount of ventilating air. The ventilating air is then drawn from the air duct into the crankcase. In this process the air passes through the hose connecting air inlet tubes to rocker cover. Under full-throttle condition, the manifold vacuum is insufficient to draw the blow-by flow through the valve. The flow goes through the hose connection in the reverse direction On vehicles with an
excessively high blow-by, the valve does not meet the requirement. This is because some of the flow will go through the hose connection to the intake manifold collector under all conditions.

You can confirm the malfunction at the moment it is detected . • While narrowing down the possible causes, CONSULT should be set in "DATA MONITOR (AUTO TRIG)" mode, especially in case the incident is intermittent. Inspect the circuit by gently shaking (or twisting) suspicious connectors, components and harness in the "DTC CONFIRMATION PROCEDURE". The moment a malfunction is found the DTC will be displayed. (Refer to GI section, "Incident Simulation Tests" in "HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT".) 2. "MANU
TRIG" • If the malfunction is displayed as soon as "DATA MONITOR" is selected, reset CONSULT to "MANU TRIG". By selecting MANU TRIG you can monitor and store the data The data can be utilized for further diagnosis, such as a comparison with the value for the normal operating condition.

SEF6740 EC-263 TROUBLE DIAGNOSIS - General Description Introduction Sensors ~ ECM Actuators ~~.~ MEF036D The engine has an ECM to control major systems such
as fuel control, ignition control, idle air control system, etc. The ECM accepts input signals from sensors and instantly drives actuators. It is essential that both input and output signals are proper and stable. At the same time, it is important that there are no problems such as vacuum leaks, fouled spark plugs, or other problems with the engine. It is much more difficult to diagnose a problem that occurs intermittently rather than continuously. Most intermittent problems are caused by poor electric connections or improper wiring In this case, careful checking of suspected circuits may help prevent the replacement of good parts. A visual check only may not find the cause of the problems. A road test with CONSULTor a circuit tester connected should be performed. Follow the "Work Flow" on the next page Before undertaking actual checks, take just a few minutes to talk with a customer who approaches with a driveability complaint. The customer can supply good information about
such problems, especially intermittent ones. Find out what symptoms are present and under what conditions they occur. A "Diagnostic Worksheet" like the example on EC-267 should be used Start your diagnosis by looking for "conventional" problems first. This will help troubleshoot driveability problems on an electronically controlled engine vehicle.

the next page. occurred Before confirming the concern, check and write down (print out using CONSULT) the Diagnostic Trouble Code (DTC), then erase the code. The DTC can be used when duplicating the incident at STEP 1/1 & IV Study the relationship between the cause, specified by DTC, and the symptom described by the customer. (The "Symptom Matrix Chart" will be useful. Refer to EC-274) Try to confirm the symptom and under what conditions the incident occurs. The "DIAGNOSTIC WORK SHEET" is useful to verify the incident. Connect CONSULT to the vehicle in DATA MONITOR (AUTO TRIG) mode and check real time diagnosis results. If the incident cannot be verified, perform INCIDENT SIMULATION TESTS. Refer to GI section If the malfunction code is detected, skip STEP IV and perform STEP V. Try to detect the Diagnostic Trouble Code (DTC) by driving in (or performing) the "DTC CONFIRMATION PROCEDURE". Check and read the DTC by using CONSULT During the DTC
verification, be sure to connect CONSULT to the vehicle in DATA MONITOR (AUTO TRIG) mode and check real time diagnosis results. STEP IV If the incident cannot be verified, perform INCIDENT SIMULATION TESTS. Refer to GI section In case the "DTC CONFIRMATION PROCEDURE" is not available, perform the "OVERALL FUNCTION CHECK" instead. The DTC cannot be displayed by this check, however, this simplified "check" is an effective alternative The "NG" result of the "OVERALL FUNCTION CHECK" is the same as the DTC detection. STEP V Take the appropriate action based on the results of STEP I through IV. If the malfunction code is indicated, proceed to TROUBLE DIAGNOSIS FOR DTC XX. If the normal code is indicated, proceed to the BASIC INSPECTION. Refer to EC-271 Then perform inspections according to the Symptom Matrix Chart Refer to EC-274 STEP VI Identify where to begin diagnosis based on the relationship study between symptom and possible
causes. Inspect the system for mechanical binding, loose connectors or wiring damage using (tracing) "Harness Layouts". Gently shake the related connectors, components or wiring harness with CONSULT set in "DATA MONITOR (AUTO TRIG)" mode. Check the voltage of the related ECM terminals or monitor the output data from the related sensors with CONSULT. Refer to EC-277 The "DIAGNOSTIC PROCEDURE" in EC section contains a description based on open circuit inspection. A short circuit inspection is also required for the circuit check in the DIAGNOSTIC PROCEDURE. For details, refer to GI section ("HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT", "Circuit Inspection"). Repair or replace the malfunction parts. . Once you have repaired the circuit or replaced a component, you need to run the engine in the same conditions and circumstances which resulted in the customers initial complaint. Perform the "DTC CONFIRMATION
PROCEDURE" and confirm the normal code (Diagnostic trouble code No. STEP VII 55) is detected. If the incident is still detected in the final check, perform STEP VI by using a different method from the previous one. Before returning the vehicle to the customer, be sure to erase the unnecessary (already fixed) DTC in ECM. (Refer to EC-252.) EC-266 TROUBLE DIAGNOSIS - General Description Diagnostic Worksheet There are many operating conditions that lead to the malfunction of engine components. A good grasp of such conditions can make troubleshooting faster and more accurate. In general, each customer feels differently about a problem.

TROUBLE DIAGNOSIS FOR OTC 11 Camshaft Position Sensor (CMPS) The camshaft position sensor is a basic component of the ECCS. It monitors engine speed and piston position These input signals to the ECM are used to control fuel injection, ignition timing and other functions. The camshaft position sensor has a rotor plate and a waveforming circuit. The rotor plate has 360 slits for a 1" (POS) signal and 4 slits for a 180 (REF) signal The wave-forming circuit consists of Light Emitting Diodes (LED) and photo diodes. The rotor plate is positioned between the LED and the photo diode. The LED transmits light to the photo diode As the rotor plate turns, the slits cut the light to generate rough-shaped • pulses. These pulses are converted into on-off signals by the wave-forming circuit and sent to the ECM. 0 Rotor plate SEF6138 :£

It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot wire that is supplied with electric current from the ECM. The temperature of the hot wire is controlled by the ECM a certain amount. The heat generated by the hot wire is reduced as the intake air flows around it. The more air, the greater
the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot wire as air flow increases. The ECM detects the air flow by means of this current change .

This cut-and-control operation is accomplished through the ECM and the EGR valve & EVAP canister purge control solenoid valve. When the ECM detects any of the following conditions, current flows through the solenoid valve. This causes the port vacuum to be discharged into the atmosphere The EGR valve and EVAP canister remain closed. • • • • • • COMPONENT Low engine coolant temperature Engine starting High-speed engine operation Engine idling Excessively high engine coolant temperature Mass air flow sensor malfunction DESCRIPTION EGR valve The EGR valve controls the amount of exhaust gas routed to
the intake manifold. Vacuum is applied to the EGR valve in response to throttle valve opening. The vacuum controls the movement of a taper valve connected to the vacuum diaphragm in the EGR valve. SEF783K EGRC-BPT valve The EGRC-BPT valve monitors exhaust pressure to activate the diaphragm, controlling throttle body vacuum applied to the EGR valve. In other words, recirculated exhaust gas is controlled in response to positioning of the EGR valve or to engine operation. Exhaust pressure SEF529K EGR valve & EVAP canister purge control solenoid valve The EGR valve & EVAP canister purge control solenoid valve ~ Vacuum signal responds to signals from the ECM. When the ECM sends an ON (ground) signal, the coil in the solenoid valve is energized. A plunger will then move to cut the vacuum signal (from the throttle body to the EGR valve and EVAP canister purge valve). When the ECM sends an OFF signal, the vacuum signal passes through the solenoid valve. The signal then reaches
the EGR valve and EVAP canister.
