PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EDS003ID
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo 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 per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo 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.
Precautions for Transfer Assembly and Transfer Control Unit ReplacementEDS0031A
lWhen replacing transfer assembly or transfer control unit, check the 4WD shift indicator pattern and
adjustment 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.
lIf OK, the position between transfer assembly and transfer control unit is correct.
lIf NG, the position is different between transfer assembly and transfer control 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.

METHODFORADJUSTMENTWITH4WDSHIFTSWITCHAT“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. Stay in the below for at least 2 seconds.
lFor A/T models, stop the vehicle and move A/T selector lever to “N” position with the brake pedal
depressed.
lFor M/T models, stop the vehicle and move M/T shift lever to the neutral position with the brake and
clutch pedal depressed.
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 toTF-46, "
How to Erase Self-diagnostic Results"(with CONSULT-II) orTF-
51, "ERASE SELF-DIAGNOSIS"(without CONSULT-II).
6. Check 4WD shift indicator lamp and 4LO indicator lamp again. Refer toTF-4, "
CHECK 4WD SHIFT INDI-
CATOR 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. Stay in the below for at least 2 seconds.
lFor A/T models, stop the vehicle and move A/T selector lever to “N” position with the brake pedal
depressed.
lFor M/T models, stop the vehicle and move M/T shift lever to the neutral position with the brake and
clutch pedal depressed.
2. Turn ignition switch “OFF”.
3. Start engine.
4. Erase self-diagnosis. Refer toTF-46, "

PRECAUTIONS
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.
PrecautionsEDS0031B
lBefore connecting or disconnecting the transfer control unit harness connector, turn ignition
switch “OFF” and disconnect the battery cables. Battery voltage is applied to transfer control unit
even if ignition switch is turned “OFF”.
lWhen connecting or disconnecting pin connectors into or
from transfer control unit, take care not to damage pin ter-
minals (bend or break).
When connecting pin connectors make sure that there are
not any bends or breaks on transfer control unit pin termi-
nals.
lBefore replacing transfer control unit, perform transfer con-
trol unit input/output signal inspection and make sure
whether transfer control unit functions properly or not.
Refer toTF-38, "
Transfer Control Unit Input/Output Signal
Reference Values".
Service NoticeEDS0031C
lAfter overhaul refill the transfer with new transfer fluid.
lCheck the fluid level or replace the fluid only with the vehicle parked on level ground.
lDuring removal or installation, keep inside of transfer clear of dust or dirt.
lDisassemblyshouldbedoneinacleanworkarea.
lBefore proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.
lCheck 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.
lAll parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
lCheck appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.
lGaskets, seals and O-rings should replaced any time the transfer is disassembled.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.
lObserve the specified torque when assembling.
lClean and flush the parts sufficiently and blow-dry them.
lBe careful not to damage sliding surfaces and mating surfaces.
lUse lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transfer.
