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.
Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to
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.
Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to
for details. Ensure entire SRS operates properly.
When only one front air bag module is activated in a collision:
1.
Replace the following components:
–
Diagnosis sensor unit
–
Crash zone sensor
–
Activated front air bag and seat belt pre-tensioner.
2.
Check the other SRS components using the table below. (Refer to “SRS is NOT activated”.)
–
Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
3.
Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to
for details. Ensure entire SRS operates properly.
Only one front air bag may inflate a crash, depending on the crash severity and whether the front occupants
are belted or unbelted. This does not indicate improper performance of the system. Perform self-diagnosis to
make sure the entire SRS operates properly.
