REMOVAL
WARNING:
Removal of front side air bag module should only be done to allow deployment of front side air bag
module prior to disposal of seatback assembly.
Only complete seatback assemblies can be replaced. Refer toSE-26, "
SEATBACK (POWER AND MAN-
UAL SEAT)"andSE-27, "SEATBACK (FRAT FOLD SEAT)".
CAUTION:
lBefore servicing the SRS, turn the ignition switch off, disconnect both battery cables and wait at
least 3 minutes.
lWhen servicing the SRS, do not work from directly in front of air bag module.
1. Remove the front seat. Refer toSE-23, "
REMOVAL".
2. Remove the seatback trim and pad. Refer toSE-26, "
SEATBACK (POWER AND MANUAL SEAT)"and
SE-27, "
SEATBACK (FRAT FOLD SEAT)".
3. Remove the seatback rear finisher and remove the retainers securing the seat cushion trim. Refer toSE-
24, "SEAT CUSHION (POWER SEAT)"andSE-25, "SEAT CUSHION (MANUAL SEAT)".
4. Remove air bag module harness clips.
5. Remove the fasteners from the front side air bag module and remove the front side air bag module.
CAUTION:
lWhen using a clip removal tool to remove the seatback
board, take care not to damage the harness for front side air
bag module.
lWhen servicing the SRS, do not work from directly in front
of air bag module.
lAlways place the front side air bag module with the mount-
ing stud side facing down.
lDo not insert any foreign objects (screwdrivers, etc.) into
air bag module or harness connectors.
lDo not disassemble air bag module.
lDo not expose front seatback assembly (side air bag mod-
ule) to temperatures exceeding 90°C(194°F).
lReplace front seatback assembly (side air bag module) if it
has been dropped or sustained an impact.
lDo not allow oil, grease or water to come in contact with the
air bag module.
lIf front side air bag module is deployed, the front seatback
assembly must be replaced.
INSTALLATION

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.

Turns ON or flashes when there is a malfunction in 4WD system.
Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately 1 sec-
ond after the engine starts if system is normal.

NOTE:
4WD warning lamp is turned on when the following one or more parts are malfunctioning.
lVehicle speed signal

lCAN communication line
lAD converter
lEngine speed signal
l4WD shift switch
lWait detection switch
lActuator motor

ATP WARNING LAMP (A/T MODELS)
When A/T selector lever is in “P” position, vehicle may move because A/T parking mechanism does not oper-
ate when transfer is under neutral condition. ATP warning lamp is turned on to indicate this condition to the
driver.
