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.

FOR FRONTAL COLLISION
To repair the SRS for a frontal collision, perform the following steps.
When SRS is activated in a collision:
V01Replace the diagnosis sensor unit.
V02Remove the air bag modules.
V03Check the SRS components using the table shown below:
lReplace any SRS components showing visible signs of damage (dents, cracks, deformation).
V04Install new air bag modules.
V05Conduct self-diagnosis using CONSULT, and ``AIR BAG'' warning lamp. Refer to ``Self-diagnosis'' for
details (RS-2025). Ensure entire SRS operates properly.
When SRS is not activated in a collision:
V01Check the SRS components using the table shown below:
lReplace any SRS components showing visible signs of damage (dents, cracks, deformation).
V02Conduct self-diagnosis using CONSULT, and ``AIR BAG'' warning lamp. Refer to ``Self-diagnosis'' for
details (RS-2025). Ensure entire SRS operates properly.
