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.

(driver and passen-
ger side)REPLACE
Install air bag mod-
ule with new bolts.1. Remove air bag module. Check harness cover and connectors for damage, ter-
minals for deformities, and harness for binding.
2-1. Install driver air bag module into the steering wheel to check fit and alignment
with the wheel.
