WHENTHESIDEAIRBAGISACTIVATEDINTHESIDECOLLISION:
1. Replace the following component:
–All parts of front seat back (including front seat back frame) with front side air bag module (on the side on
which front side air bag is activated)
–Diagnosis sensor unit
–Side air bag (satellite) sensor
2. Check the SRS components and the related parts using the table shown below.
–Replace any SRS components and the related parts showing visible signs of damage (dents, cracks,
deformation).
3. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer toSRS-15, "
SRS Operation
Check". Ensure entire SRS operation properly.
WHEN SRS IS NOT ACTIVATED IN THE SIDE COLLISION:
1. Check the SRS components and the related parts using the table shown below.
–Replace any SRS components and the related parts showing visible signs of damage (dents, cracks,
deformation).
2. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer toSRS-15, "
