SRS Warning Light Circuit Malfunction

SRS Warning Light Circuit Malfunction

CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter.

When the SRS is normal, the SRS warning light lights up for approx. 6 seconds after the ignition switch is turned from the LOCK position to ON position, and then turns off automatically.

If there is a malfunction in the SRS, the SRS warning light lights up to inform the driver of the abnormality. When terminals TC and CG of the DLC3 are connected, the DTC is displayed by blinking the SRS warning light.

The signal to make the SRS warning light light up is transmitted from the airbag sensor assembly to the combination meter through multiplex communication system.
