SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: SRS Warning Light does not Come ON

SRS Warning Light does not Come ON

DESCRIPTION

The SRS warning light is located on the combination meter. When the power switch is turned from OFF to ON (IG), the SRS warning light illuminates. If the SRS is normal, the SRS warning light turns off automatically after approximately 6 seconds. If there is a malfunction in the SRS, the SRS warning light remains illuminated even after approximately 6 seconds have passed. When terminals TC and CG of the DLC3 are connected, the DTCs are communicated through SRS warning light blinking patterns.
