FOR FRONTAL COLLISION
To repair the SRS for a frontal collision, perform the following steps.
When SRS (except the side airbag) is activated in a collision:
p1Replace the diagnosis sensor unit.
p2Remove the air bag modules (except the side airbag module) and seat belt pre-tensioner assemblies.
p3Check the SRS components using the table shown below:
lReplace any SRS components showing visible signs of damage (dents, cracks, deformation).
p4Install new air bag modules (except the side airbag module) and seat belt pre-tensioner assemblies.
p5Conduct self-diagnosis using CONSULT-II, and ªAIR BAGº warning lamp. Refer to ªSRS Operation
Checkº for details (RS-37). Ensure entire SRS operates properly.
When SRS is not activated in a collision:
p1Check the SRS components using the table shown below:
lReplace any SRS components showing visible signs of damage (dents, cracks, deformation).
p2Conduct self-diagnosis using CONSULT-II, and ªAIR BAGº warning lamp. Refer to ªSRS Operation

CAUTION:
lThe rotation of the spiral cable (SRS ªAir bagº component
part) is limited. If the steering gear must be removed, set
the front wheels in the straight-ahead direction. Do not
rotate the steering column while the steering gear is
removed.
lRemove the steering wheel before removing the steering
lower joint to avoid damaging the SRS spiral cable.
