Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EDS003IE
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 Differential Case Assembly and Differential Lock Control Unit
Replacement
EDS003AG
lWhen replacing differential case assembly or differential lock control unit, check the DIFF LOCK indicator
pattern and adjustment of the position between differential case assembly and differential lock control unit
if necessary.
CHECK DIFF LOCK INDICATOR LAMP
1. Start engine. Run engine for at least 10 seconds.
2. Turn 4WD shift switch to “4LO” and confirm 4LO indicator lamp is turned on. Refer toTF-16, "
4WD SHIFT
SWITCH AND INDICATOR LAMP".
3. Stop vehicle and turn differential lock mode switch to “ON”.
4. Drive vehicle at 7 km/h (4 MPH) or less.
NOTE:
Differential case assembly must be given a rotation from rear left wheel and rear right wheel.
5. Check if DIFF LOCK indicator lamp flashes to turn on.
6. Check if DIFF LOCK indicator lamp and 4LO indicator lamp are changed properly as follows.
lIf each indication and state is OK, rear final drive assembly and differential lock control unit is working cor-
rectly.
lIf each indication and state is NG, rear final drive assembly and differential lock control unit is not working
correctly. Refer toRFD-34, "

PRECAUTIONS
METHOD FOR ADJUSTMENT
1. Perform erase self-diagnosis with differential lock control unit. Refer toRFD-52, "How to Erase Self-diag-
nostic Results".
2. Check differential lock control unit input/output signal. Refer toRFD-48, "
Differential Lock Control Unit
Input/Output Signal Reference Values".
3. Check DIFF LOCK indicator lamp. Refer toRFD-33, "
CHECK DIFF LOCK INDICATOR LAMP".
lIf DIFF LOCK indicator lamp is not proper according to the above patterns.
Install new differential lock control unit or check for mechanical malfunction of rear final drive assembly
and retry the above (DIFF LOCK indicator lamp) check.
(If differential lock control unit or rear final drive assembly is replaced from another vehicle, the new dif-
ferential control unit must be replaced first.)
PrecautionsEDS003AH
lBefore connecting or disconnecting differential lock control
unit harness connector, turn ignition switch “OFF” and dis-
connect the battery cables. Because battery voltage is
applied to differential lock control unit even if ignition
switch is turned “OFF”.
lWhen connecting or disconnecting pin connectors into or
from differential lock 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 differential lock control unit pin
terminal.
lBefore replacing differential lock control unit, perform dif-
ferential lock control unit input/output signal inspection
and make sure whether differential lock control unit func-
tions properly or not. Refer toRFD-48, "
Differential Lock
Control Unit Input/Output Signal Reference Values".

Service Notice or PrecautionEDS003AI
lCheck for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.
lOverhaul should be done in a clean work area, it is preferable to work in dust proof area.
lBefore disassembly completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
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 be replaced any time when the unit is disassembled.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
lClean and flush the parts sufficiently and blow-dry them.
lBe careful not to damage sliding surfaces and mating surfaces.
lWhen applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
lAlways use shop paper for cleaning the inside of components.
lAvoid using cotton gloves or shop rags to prevent entering of lint.
lDuring assembly, observe the specified tightening torque, and apply new differential gear oil, petroleum
jelly, or multi-purpose grease as specified for each vehicle, if necessary.
Wiring Diagrams and Trouble DiagnosisEDS003AJ
When reading wiring diagrams, refer to the following:
lGI-15, "How to Read Wiring Diagrams".
lPG-4, "POWER SUPPLY ROUTING CIRCUIT".
When performing trouble diagnosis, refer to the following:
lGI-11, "How to Follow Trouble Diagnoses".
lGI-24, "How to Perform Efficient Diagnosis for an Electrical Incident".
