Supplemental Restraint System (SRS) ``AIR
BAG''
The Supplemental Restraint System ``AIR BAG'' used along with a seat belt, helps to reduce the risk or
severity of injury to the driver and front passenger in a frontal collision. The SRS composition which is avail-
able to NISSAN MODEL D22 is as follows (The composition varies according to the destination and optional
equipment.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), a diagnosis sensor unit, warning lamp, wiring harness and spi-
ral cable.
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 dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation either just
before the harness connectors or for the complete harness are related to the SRS.
PRECAUTION
RS-2002

Precautions for SRS ``AIR BAG'' and ``SEAT
BELT PRE-TENSIONER'' Service
lDo not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
lBefore servicing the SRS, turn ignition switch ``OFF'', disconnect both battery cables and wait at least
3 minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag to deploy.
Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
lDiagnosis sensor unit must always be installed with their arrow marks ``S'' pointing towards the front of
the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
lThe spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt
to turn steering wheel or column after removal of steering gear.
lHandle air bag module carefully. Always place driver and passenger air bag modules with the pad side
facing upward.
lConduct self-diagnosis to check entire SRS for proper function after replacing any components.
lAfter air bag inflates, the front instrument panel assembly should be replaced if damaged.

CAUTION:
Do not use electrical test equipment to check SRS circuit.
1. Check operation of ``AIR BAG'' warning lamp.
After turning ignition key to ``ON'' position, the warning lamp
illuminates. The ``AIR BAG'' warning lamp will go off after
about 7 seconds if no malfunction is detected. If any of the
following warning lamp conditions occur, immediately check
the air bag system. Refer to RS-2025 for details.
lThe ``AIR BAG'' warning lamp does not illuminate when the
ignition switch is turned ``ON''.
lThe ``AIR BAG'' warning lamp does not go off about 7 sec-
onds after the ignition switch is turned ``ON''.
lThe ``AIR BAG'' warning lamp blinks after about 7 seconds
after the ignition switch is turned ``ON''.
2. Visually check SRS components
(1) Diagnosis sensor unit
lCheck diagnosis sensor unit and bracket for dents, cracks or
deformities.
lCheck connectors for damage, and terminals for deformities.
(2) Air bag module and steering wheel
