PRECAUTIONS AND PREPARATION
Observe the following precautions to ensure safe and proper servicing.

PRECAUTIONS FOR SUPPLEMENTAL RESTRAINT SYSTEM (SRS) ``AIR BAG'' AND ``SEAT BELT PRETENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. The SRS system composition which is available to NISSAN MODEL L30 is as follows (The composition varies according to optional equipment.): q For a frontal collision The Supplemental Restraint System consists of driver air bag module (located in the center of the steering wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable. q For a side collision The Supplemental Restraint System consists of front side air bag module (located in the outer side of front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring harness, warning lamp (one of components of air bags for a frontal collision). Information necessary to service the system safely is included in the RS section of this Service Manual. WARNING: q To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance should be performed by an authorized NISSAN dealer. q Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by intentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the RS section. q Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. Spiral cable and wiring harnesses (except ``SEAT BELT PRE-TENSIONER'') covered with yellow insulation either just before the harness connectors or for the complete harness are related to the SRS.

SGI646

PRECAUTIONS FOR NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM -- NATS)
NVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS (NATS).

GI-2

PRECAUTIONS AND PREPARATION (Cont'd)
Both of the originally supplied ignition key IDs have been NVIS (NATS) registered. The security indicator is located on the instrument panel. The indicator blinks when the ignition switch is in ``OFF'' or ``ACC'' position. Therefore, NVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system. q When NVIS (NATS) detects trouble, the security indicator lamp lights up while igntion switch is in ``On'' position. This lighting up indicates that the anti-theft is not functioning, so prompt service is required. q When servicing NVIS (NATS) (trouble diagnoses, system initialization and additional registration of other NVIS (NATS) ignition key IDs), CONSULT-II hardware and CONSULT-II NVIS (NATS) software is necessary. Regarding the procedures of NVIS (NATS) initialization and NVIS (NATS) ignition key ID registration, refer to CONSULT-II operation manual, IVIS/NVIS (NATS). Therefore, CONSULT-II NVIS (NATS) software (program card and operation manual) must be kept strictly confidential to maintain the integrity of the anti-theft function. q When servicing NVIS (NATS) (trouble diagnoses, system initialization and additional registration of other NVIS (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 five key IDs can be registered into NVIS (NATS). q When failing to start the engine first time using the key of NVIS (NATS), start as follows. a) Leave the ignition key in ``ON'' position for approximately 5 seconds. b) Turn ignition key to ``OFF'' or ``LOCK'' position and wait approximately 5 seconds. c) Repeat step 1 and 2 again. d) Restart the engine while keeping the key separate from any others on key-chain.

PRECAUTIONS AND PREPARATION General Precautions
q

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 inflammable materials. Special care should be taken when handling any inflammable 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. 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, 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.

SGI234

GI-4

PRECAUTIONS AND PREPARATION General Precautions (Cont'd)
Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly. q Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins and self-locking nuts, etc. with new ones. q Replace inner and outer races of tapered roller bearings and needle bearings as a set. q Arrange the disassembled parts in sequence with their assembled locations. q Do not touch the terminals of electrical components which use microcomputers (such as ECM). Static electricity may damage internal electronic components. q After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection. q Use only the fluids and lubricants specified in this manual. q Use approved bonding agent, sealants or their equivalents when required. q Use tools and recommended special tools where specified for safe and efficient service repairs. q When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks. q Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner. q Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically. Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire. WARNING: To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness connectors which are related to the engine control system and TCM (Transmission Control Module) system. The connectors should be disconnected only when working according to the WORK FLOW of TROUBLE DIAGNOSES in EC and AT sections.

q

q q

AGI011

Before connecting or disconnecting any harness connector for the multiport fuel injection system or ECM: Turn ignition switch to OFF position. Disconnect negative battery terminal, otherwise, there may be damage to ECM. Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure. Be careful not to jar components such as ECM 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: q Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst. q When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary. q 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 inflammable material. Keep inflammable material off the exhaust pipe and the three way catalyst.

PRECAUTIONS FOR HOSES Hose Removal and Installation
q

To prevent damage to rubber hose, do not pry off rubber hose with tapered tool or screwdriver.

skin disorders develop, obtain medical advice without delay. practicable, degrease components prior to handling. qWhere 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.
qWhere qIf

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 the ground, down sewers, drains, or into water courses. The regulations concerning pollution vary from country to country.

Precautions for Fuel
Use unleaded gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (research octane number 91). CAUTION: Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel other than that specified could adversely affect the emission control devices and systems, and could also affect warranty coverage validity.

Precautions for Air Conditioning
Use an approved refrigerant recovery unit anytime the air conditioner system must be discharged. Refer to HA-62 section (``HFC-134a (R-134a) Service Procedure'', ``SERVICE PROCEDURES'') for specific instructions.

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, recreate 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 conditions/environment under which the owner experiences an electrical incident. The section is broken into the six following topics: q Vehicle vibration q Heat sensitive q Freezing q Water intrusion q Electrical load q Cold or hot start up Get a thorough description of the incident from the customer. It is important for simulating the conditions of the problem.

VEHICLE VIBRATION
The problem may occur or become worse while driving on a rough road or when the engine is vibrating (idle with A/C 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.

To inspect components under the hood, start by verifying the integrity of ground connections. Refer to GI-29. First check that the system is properly grounded. Then, check for loose connec- EC tion by gently shaking the wiring or components as previously explained. Using the wiring diagrams, inspect the wiring for conFE tinuity.

AT

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 FA for possible damage or pinching.

HEAT SENSITIVE

RA

The owner's problem may occur during hot weather or after car has sat for a short time. In such cases, you will want to check BR for a heat sensitive condition. To determine if an electrical component is heat sensitive, heat ST the component with a heat gun or equivalent. Do not heat components above 60C (140F). If incident occurs while heating the unit, either replace or properly insulate RS the component.
SGI842

FREEZING

BT

SGI843

The customer may indicate the incident goes away after the car warms up (winter time). The cause could be related to water HA 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 the car overnight. Make sure it will get EL cold enough to demonstrate the complaint. Leave the car parked outside overnight. In the morning, do a quick and thorough diagnosis of those electrical components which could be IDX 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
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 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
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.

Circuit Inspection
INTRODUCTION
In general, testing electrical circuits is an easy task if approached logically. 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 SHORT A circuit is open when there is no continuity through a section of the circuit. There are two types of shorts.
q

SHORT CIRCUIT SHORT TO GROUND

When a circuit contacts another circuit and causes the normal resistance to change. When a circuit contacts a ground source and grounds the circuit.

Continuity check method

The continuity check is used to find an open in the circuit. The Digital Multimeter (DMM) set on the resis- FE tance function will indicate an open circuit as over limit (no beep tone or no ohms symbol). Make sure no power is supplied to the checked component. Always start with the DMM at the highest resistance CL level. To help in understanding the diagnosis of open circuits, please refer to the schematic above. 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). Connect one probe of the DMM to the fuse block terminal on the load side. 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 was 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 was 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. 1. 2. 3. 4.

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 voltage. This is RS 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. BT 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). HA 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). EL 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).

TESTING FOR ``SHORTS'' IN THE CIRCUIT
To simplify the discussion of shorts in the system, please refer to the schematic below.

AGI084

Resistance check method
1. Disconnect the battery negative cable and remove the blown fuse. 2. Disconnect all loads (SW1 open, relay disconnected and solenoid disconnected) powered through the fuse. 3. Connect one probe of the ohmmeter to the load side of the fuse terminal. Connect the other probe to a known good ground. 4. With SW1 open, check for continuity. Continuity: short is between fuse terminal and SW1 (point A). No continuity: short is further down the circuit than SW1. 5. Close SW1 and disconnect the relay. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity. Continuity: short is between SW1 and the relay (point B). No continuity: short is further down the circuit than the relay. 6. Close SW1 and jump the relay contacts with jumper wire. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity. Continuity: short is between relay and solenoid (point C). No continuity: check solenoid, retrace steps.

Voltage check method
1. Remove the blown fuse and disconnect all loads (i.e., SW1 open, relay disconnected and solenoid disconnected) powered through the fuse. 2. Turn the ignition key to the ON or START position. Verify battery voltage at the battery + side of the fuse terminal (one lead on the battery + terminal side of the fuse block and one lead on a known good ground). 3. 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. 4. 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 further down the circuit than the relay. 5. With SW1 closed, relay contacts jumped with fused jumper wire check for voltage.

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. For detailed ground distribution information, refer to ``GROUND DISTRIBUTION'', in EL-20 section.

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: 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 voltage drop -- Accumulated method
1. 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. 2. Operate the circuit. 3. 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.

Measuring voltage drop -- Step by step
The step by step method is most useful for isolating excessive drops in low voltage systems (such as those in ``Computer Controlled Systems''). GI Circuits in the ``Computer Controlled System'' operate on very low amperage. The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the system. Such resistance variation may be caused by poor connection, improper installation, improper MA wire gauge or corrosion. The step by step voltage drop test can identify a component or wire with too much resistance.
