PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NHS00073
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 SRS 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 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.
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceNHS00074

Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.

Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.

Diagnosis sensor unit must always be installed with their arrow marks “ ⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before instal-
lation and replace as required.

The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steer-
ing wheel and column after removal of steering gear.

Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and seat mounted front side air bag module standing with the stud bolt side facing
down.

Conduct self-diagnosis to check entire SRS for proper function after replacing any components.

After air bag inflates, the front instrument panel assembly should be replaced if damaged.

Always replace instrument panel pad following front passenger air bag deployment.

Disposal, recycling, and transportation of air bag modules and seat belt pre-tensioners should be per-
formed in compliance with applicable federal, state and local laws and regulations.
Occupant Classification System PrecautionNHS0009N
Replace occupant classification system control unit and passenger front seat cushion as an assembly.

REMOVAL
CAUTION:

Before servicing SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3
minutes.

Always work from the side of driver air bag module.

Do not use air tools or electric tools for servicing.
1. Remove the side lids.
2. Remove the right and left side TORX bolts (T30).
3. Lift up the driver air bag module.
4. Disconnect the air bag harness connector, and remove the driver air bag module.
NOTE:

For installing / removing driver air bag module connector,
insert thin screwdriver wrapped in tape into notch, lift lock and
remove connector.

Install connector with lock raised, and push lock into connec-
tor.

After installing the connector, make sure that the lock is
pushed securely into it.

CAUTION:

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
Install in the reverse order of removal.
CAUTION:

Fix the air bag module harness (shown as A in the figure) to
the harness fixing hook (shown as B in the figure).

Be careful not to damage the harness while installing.

Tighten the special bolts after exactly adjusting the centers of fixing holes on the air bag module
side and the steering wheel side. If the holes are misaligned, the bolt threads are damaged and the
module is not installed securely.

After the work is completed, make sure no system malfunction is detected by air bag warning
lamp.

In case that malfunction is detected by the air bag warning lamp, reset by the self-diagnosis func-
tion and delete the memory by CONSOULT–II.

In case that malunction is still detected after the above operation, peform self-diagnosis to repair
malfunctions. Refer to Refer to SRS-20, "
SRS Operation Check" .

CAUTION:

Before servicing SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3
minutes.

Do not use air tools or electric tools for servicing.
1. Remove driver air bag module. Refer to SRS-42, "
Removal and Installation" .
2. Disconnect steering switch harness connector.
3. Set the steering wheel in the neutral position.
4. Removal steering wheel. Refer to PS-12, "

INSTALLATION
Install in the reverse order of removal.
CAUTION:

The spiral cable may snap by steering operation if the cable
is installed in an improper position.

The neutral position is set as follows.
Turn quietly the spiral cable clockwise to the end position.
Then turn it counterclockwise (about 2 and half turns) and
stop turning at the point on which the stopper insertion
holes are in the same position.
The service part is installed in the neutral position by the
stopper and can be set without adjusting after the stopper
is removed.

Do not turn the spiral cable rashly and also beyond the limit
number of turns. (These will cause cable snap.)

Adjust the spiral cable locating pin (showed as A inthe fig-
ure) to the steering wheel locating pin hole (showed as C in
the figuer).

Secure the air bag harness with the harness fixing hook.

After the work is completed, make sure no system malfunc-
tion is detected by air bag warning lamp.

In case that malfunction is detected by the air bag warning
lamp, reset by the self-diagnosis function and delete the
memory by CONSULT −II.

In case that malfunction is still detected after the above
operation, perform self-diagnosis to repair malfunctions.
