WHEELS & TIRES SPECIFICATION

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the SRS AIRBAG article and SEAT BELTS article.

WARNINGTo 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 must be performed by an authorized NISSAN/INFINITI dealer. Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS AIRBAG . Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Information. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNINGWhen working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

Note. This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYSTEM). Remove and install all control units after disconnecting both battery cables with the ignition knob in the "LOCK" position. Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mechanism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, follow the procedure below before starting the repair operation.

Procedures without Cowl Top Cover

When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc.

Scheme 34
  1. 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.
  2. 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.
  3. 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.
  4. Before starting repairs which do not require battery power: Turn off ignition switch. Disconnect the negative battery terminal.
  5. If the battery terminals are disconnected, recorded memory of radio and each control unit is erased.
  6. To prevent serious burns: Avoid contact with hot metal parts. Do not remove the radiator cap when the engine is hot.
  7. Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner.
  8. 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.
  9. Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly.
  10. Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones.
  11. Replace inner and outer races of tapered roller bearings and needle bearings as a set.
  12. Arrange the disassembled parts in accordance with their assembled locations and sequence.
  13. Do not touch the terminals of electrical components which use microcomputers (such as ECM). Static electricity may damage internal electronic components.
  14. After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
  15. Use only the fluids and lubricants specified in this service information.
  16. Use approved bonding agent, sealants or their equivalents when required.
  17. Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs.
  18. When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
  19. Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate covers. Take caution that keys, buckles or buttons do not scratch paint.
WARNINGTo 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 the ENGINE CONTROL SYSTEM (VK56DE) article and the AUTOMATIC TRANSMISSION article. .

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.

  1. Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
  2. When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary.
  3. 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.

Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research octane number 91). E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) may only be used in vehicles specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models).

CAUTIONDo not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect the emission control devices and systems, and could also affect the warranty coverage validity.

Scheme 35

Scheme 35: Multiport Fuel Injection System or Engine Control System
  1. 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.
  2. Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure.
  3. Be careful not to jar components such as ECM and mass air flow sensor.

  1. To prevent damage to rubber hose, do not pry off rubber hose with tapered tool or screwdriver.
  2. To reinstall the rubber hose securely, make sure that hose insertion length and orientation is correct. (If tube is equipped with hose stopper, insert rubber hose into tube until it butts up against hose stopper.)

Scheme 38

Scheme 38: HOSE CLAMPING

Scheme 39

Scheme 39
  1. If old rubber hose is reused, install hose clamp in its original position (at the indentation where the old clamp was). If there is a trace of tube bulging left on the old rubber hose, align rubber hose at that position.
  2. Discard old clamps; replace with new ones.
  3. After installing plate clamps, apply force to them in the direction of the arrow shown in the illustration, tightening rubber hose equally all around.

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

  1. Avoid prolonged and repeated contact with oils, particularly used engine oils.
  2. Wear protective clothing, including impervious gloves where practicable.
  3. Do not put oily rags in pockets.
  4. Avoid contaminating clothes, particularly underpants, with oil.
  5. Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regularly.
  6. First aid treatment should be obtained immediately for open cuts and wounds.
  7. Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
  8. 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.
  9. Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
  10. If skin disorders develop, obtain medical advice without delay.
  11. Where practical, degrease components prior to handling.
  12. 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

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 sources.

  3. While holding the wire of the male terminal, try to insert the male terminal into the female terminal. CAUTION: Do not force the male terminal into the female terminal with your hands.
  4. While moving the connector, check whether the male terminal can be easily inserted or not. If the male terminal can be easily inserted into the female terminal, replace the female terminal.

Waterproof Connector Inspection

If water enters the connector, it can short interior circuits. This may lead to intermittent problems.

Check the following items to maintain the original waterproof characteristics.

RUBBER SEAL INSPECTION

Scheme 60

Scheme 60
  1. Most waterproof connectors are provided with a rubber seal between the male and female connectors. If the seal is missing, the waterproof performance may not meet specifications.
  2. The rubber seal may come off when connectors are disconnected. Whenever connectors are reconnected, make sure the rubber seal is properly installed on either side of male or female connector.

WIRE SEAL INSPECTION

  1. The wire seal must be installed on the wire insertion area of a waterproof connector. Be sure that the seal is installed properly.

Terminal Lock Inspection

Check for unlocked terminals by pulling wire at the end of connector.

An unlocked terminal may create intermittent signals in the circuit.

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.

CAUTIONDo not spray water directly on any electrical components.

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.

VOLTAGE DROP TESTS

  1. 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.
  2. Check the wire in the illustration. When measuring resistance with DMM, 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.
  3. Unwanted resistance can be caused by many situations as follows: Undersized wiring (single strand example) Corrosion on switch contacts Loose wire connections or splices.
  4. If repairs are needed always use wire that is of the same or larger gauge.

Measuring Voltage Drop - Accumulated Method

  1. Connect the DMM across the connector or part of the circuit you want to check. The positive lead of the DMM should be closer to power and the negative lead closer to ground.
  2. Operate the circuit.
  3. The DMM 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

Scheme 65

Scheme 65
  1. The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those in "Computer Controlled Systems").
  2. Circuits in the "Computer Controlled System" operate on very low amperage.
  3. 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 wire gauge or corrosion.
  4. The step by step voltage drop test can identify a component or wire with too much resistance.
