SRS WARNING LIGHT CIRCUIT MALFUNCTION (DOES NOT LIGHT
UP, WHEN IGNITION SWITCH IS TURNED TO ON)
CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter assy.
When the SRS is normal, the SRS warning light comes on for approx. 6 seconds after the ignition switch
is turned from the LOCK position to the ON position, and then it turns off automatically.
If there is a malfunction in the SRS, the SRS warning light comes on to inform a trouble to the driver.
When between terminal TC and terminal CG of the DLC3 are connected, the DTC is displayed by blinking
the SRS warning light.

2 CHECK AIR BAG SENSOR ASSY CENTER
(a) Turn the ignition switch to the LOCK position.
(b) Disconnect the negative (±) terminal cable from the battery, and wait for at least 90 seconds.
(c) Disconnect the connectors from the airbag sensor assy center.
(d) Connect the negative (±) terminal cable to the battery, and turn the ignition switch to the ON position.
(e) Check that the SRS warning light operation.
