(a) When the vehicle is damaged in a collision even when the SRS parts are not deployed.

(b) When an SRS system DTC is output.


1. PRECAUTION FOR AIRBAG SENSORS

(a) Perform a diagnostic system check.

(b) When the SRS parts are deployed (including when only an airbag or pretensioner is deployed) due to a collision, be sure to replace all sensors in the damaged areas (anywhere in need of repair) and airbag ECU assembly.

No defects are found.

If any of the defects is found or an airbag sensor has detected a major collision, replace the airbag sensor with a new one.
