SRS WARNING LIGHT CIRCUIT MALFUNCTION (ALWAYS LIGHT UP, WHEN IGNITION SWITCH IS ACC OR LOCK POSITION)
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 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 DTCs are displayed by blinking the SRS warning light.
The signal to make the SRS warning light to comes on is transmitted from the airbag sensor assy center to the combination meter assy through multiplex
communication system.
