COLLISION DIAGNOSISPFP:00015
For Frontal CollisionBHS0004O
To repair the SRS, perform the following steps.
When SRS (except the front side air bag and side curtain air bag modules) is activated in a collision:
1. Replace the diagnosis sensor unit.
2. Remove the air bag modules (except the front side air bag modules and side curtain air bag modules),
crash zone sensor assembly, bracket and seat belt pre-tensioner assemblies.
3. Check the SRS components using the table below:
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
4. Install new air bag modules (except the front side air bag modules and side curtain air bag modules) crash
zone sensor assembly, bracket and seat belt pre-tensioner assemblies.
5. Perform self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-16, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
When SRS is not activated in a collision:
1. Check the SRS components using the table below:
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
2. Perform self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-16, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
