Vehicle Damage Warnings

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 SR and SB section of this Service Manual.

WARNING:
^ 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 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 SR section.
^ Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

Precaution for Transfer Assembly and Transfer Control Unit Replacement
When replacing transfer assembly or transfer control unit, check the 4WD shift indicator lamp as follows.

1. Turn ignition switch ON.
2. Check 4WD shift indicator lamp is turned ON for approximately 1 second.
^ If OK, the position between transfer assembly and transfer control unit is correct.
^ If NG, the position is different between transfer assembly and transfer control unit.
Adjust the position between transfer assembly and transfer control unit. See METHOD FOR POSITION ADJUSTMENT that follows.

METHOD FOR POSITION ADJUSTMENT
1. Start engine. Run the engine for at least 10 seconds.
2. Stop vehicle and move A/T selector lever to N position with brake pedal depressed. Stay in N for at least 2 seconds.
3. Turn 4WD shift switch to 2WD position. Stay in 2WD for at least 2 seconds.
4. Turn ignition switch OFF.
5. Start engine.
6. Erase self-diagnosis. Refer to DLN-17, "CONSULT-III Function (ALL MODE AWD/4WD)". Consult-III Function (All Mode AWD/4WD)
7. Check 4WD shift indicator lamp. Refer to DLN-6, "Preliminary Check". Preliminary Check
If 4WD shift indicator lamp does not indicate 2WD, install new transfer control unit and retry the above check.

Precaution

^ Before connecting or disconnecting the transfer control unit harness connector, turn ignition switch "OFF" and disconnect battery cables. Failure to do so may damage the transfer control unit. Battery voltage is applied to transfer control unit even if ignition switch is turned "OFF".

^ When connecting or disconnecting pin connectors into or from transfer control unit, take care not to damage pin terminals (bend or break).
When connecting pin connectors make sure that there are not any bends or breaks on transfer control unit pin terminals.

^ Before replacing transfer control unit, perform transfer control unit input/output signal inspection and make sure transfer control unit functions properly. Refer to DLN-79, "Reference Value". Reference Value

Service Notice
^ After overhaul refill the transfer with new transfer fluid.
^ Check the fluid level or replace the fluid only with the vehicle parked on level ground.
^ During removal or installation, keep inside of transfer clear of dust or dirt.
^ Disassembly should be done in a clean work area.
^ Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter.
^ Check for the correct installation status prior to removal or disassembly. If matchmarks are required, be certain they do not interfere with the function of the parts when applied.
^ All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly.
^ Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them with new ones if necessary.
^ Gaskets, seals and O-rings should be replaced any time the transfer is disassembled.
^ In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tightening sequence is specified, use it.
^ Observe the specified torque when assembling.
^ Clean and flush the parts sufficiently and blow-dry them.
^ Be careful not to damage sliding surfaces and mating surfaces.
^ Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere with the operation of the transfer.
