## for Preparation Click here

## DESCRIPTION

The SRS warning light is located on the combination meter. When the SRS is normal, the SRS warning light illuminates for approximately 6 seconds after the ignition switch is turned from OFF to ON, and then turns OFF automatically. If there is a malfunction in the SRS, the SRS warning light illuminates to inform the driver. When terminals TC and CG of the DLC3 are connected, the DTCs are communicated through SRS warning light blinking patterns.
