DRIVER AIR BAG MODULE

CAUTION:

Always work from the side of driver air bag module.

Always place driver air bag module with pad side facing
upward.

Do not insert any foreign objects (screwdriver, etc.) into
driver air bag module.

Do not disassemble driver air bag module.

Do not use old bolts after removal; replace with new bolts.

Do not expose the driver air bag module to temperatures
exceeding 90°C (194°F).

Replace driver air bag module if it has been dropped or sus-
tained an impact.

Do not allow oil, grease or water to come in contact with the
driver air bag module.
INSTALLATION
1. Connect harness connector to air bag module.
CAUTION:
Fix air bag harness on the hook for harness fixing.
2. Install the air bag module with new TORX bolts (T30).
NOTE:
Align air bag module side hole with steering wheel side hole, and then tighten special bolts when installing
air bag module. Thread is damaged and installation is incorrect if both holes are not aligned.
3. Install side lids.
4. Connect both battery cables.
5. Check SRS air bag warning lamp to make sure that the system works normally after finishing work.
6. If SRS air bag warning lamp indicates a DTC exists, reset with self-diagnosis and erase the memory using
CONSULT-II.
7. After the work is completed, perform self-diagnosis to make sure that no malfunction is detected. Refer to
SRS-16, "
SRS Operation Check" .

SPIRAL CABLE

7. Disconnect the horn switch connector and spiral cable connec-
tor.
NOTE:
Disconnect the horn switch connector, and then the spiral cable
connector.
CAUTION:
Do not tap or bump the steering wheel.
8. Loosen screws. While pushing upper plastic tab, remove spiral cable.
INSTALLATION
Install in the reverse order of removal.
CAUTION:

If it is mounted in the inappropriate position, spiral cable
may be cut when performing steering operation.

Also, with the steering linkage disconnected the cable may
snap by turning the steering wheel beyond the limited num-
ber of turns. The spiral cable can be turned counterclock-
wise about 2.5 turns from the right end position.

Do not twist spiral cable freely or excessively after it
becomes tight (doing so may cause the cable to be torn
off).

Secure air bag harness to the harness fixing hook.

Check SRS air bag warning lamp to make sure that the sys-
tem works normally after finishing work.

If SRS air bag warning lamp indicates a DTC exists, reset
with self-diagnosis and erase the memory using CONSULT-
II.

After the operation above, if SRS air bag warning lamp still
shows a non-standard condition, perform system trouble
diagnosis again, and repair or replace the indicated compo-
nent. Refer to SRS-16, "
SRS Operation Check" .

PRECAUTIONPFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BKS001TD
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:

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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper 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.

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.
