PRECAUTIONS

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

INFOID:0000000006179494

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 Man-

ual.

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 har-

ness connectors.

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

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion 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 for Transfer Assembly and Transfer Control Unit Replacement

INFOID:0000000006179495

When replacing transfer assembly or transfer control unit, check the 4WD shift indicator pattern and adjust-

ment of the position between transfer assembly and transfer control unit if necessary.

CHECK 4WD SHIFT INDICATOR PATTERN

1. Set 4WD shift switch to 2WD, 4H, 4LO, 4H and 2WD in order. Stay at each switch position for at least 2

seconds.

2. Confirm 4WD shift indicator lamp and 4LO indicator lamp are changed properly as follows.

• If inspection results are normal, the position between transfer assembly and transfer control unit is cor-

rect.

• If inspection results are abnormal, the position is different between transfer assembly and transfer con-

trol unit.

Adjust the position between transfer assembly and transfer control unit. Refer to pattern table below.

Transfer position adjustment pattern

NOTE:
Method of adjustment can be chosen voluntarily, according to location of 4WD shift switch.

METHOD FOR ADJUSTMENT WITH 4WD SHIFT SWITCH AT 2WD

Select Adjustment Pattern

1. Start engine. Run engine for at least 10 seconds.
2. Check 4WD shift indicator lamp and 4LO indicator lamp.

Pattern A

1. Stop vehicle and move A/T selector lever to N position with brake pedal depressed. Stay in N for at least 2

seconds.

2. Turn 4WD shift switch to 4LO position. Stay in 4LO for at least 2 seconds.
3. Turn ignition switch OFF.
4. Start engine.
5. Erase self-diagnosis. Refer to 

DLN-16, "CONSULT-III Function (ALL MODE AWD/4WD)"

.

6. Check 4WD shift indicator lamp and 4LO indicator lamp again. Refer to CHECK 4WD SHIFT INDICATOR

PATTERN.

If 4WD shift indicator lamp and 4LO indicator lamp do not indicate proper pattern, install new transfer con-

trol unit and retry the above check.

Pattern B

1. Stop vehicle and move A/T selector lever to N position with brake pedal depressed. Stay in N for at least 2

seconds.

2. Turn ignition switch OFF.
3. Start engine.
4. Erase self-diagnosis. Refer to 

DLN-16, "CONSULT-III Function (ALL MODE AWD/4WD)"

.

5. Check 4WD shift indicator lamp and 4LO indicator lamp again. Refer to CHECK 4WD SHIFT INDICATOR

PATTERN.

If 4WD shift indicator lamp and 4LO indicator lamp do not indicate proper pattern, install new transfer con-

trol unit and retry the above check.

METHOD FOR ADJUSTMENT WITH 4WD SHIFT SWITCH AT 4H OR 4LO

Precaution

INFOID:0000000006179496

• Before connecting or disconnecting the transfer control unit

harness connector, turn ignition switch OFF and disconnect

the battery cables. Battery voltage is applied to transfer con-

trol 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 termi-

nals (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 con-

trol unit input/output signal inspection and make sure transfer

control unit functions properly. Refer to 

DLN-55, "Reference

Value"

.

Service Notice

INFOID:0000000006179497

• 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 cer-

tain 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 a new ones if necessary.

• Gaskets, seals and O-rings should replaced any time the transfer is disassembled.

• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-

ening sequence is specified, use it.

• Observe the specified torque when assembling.

• Clean and flush the parts sufficiently and blow-dry them.
