SRS Warning Indicator
The supplemental restraint system (SRS) warning indicator consists of a red light emitting diode (LED) behind a supplemental restraint system (SRS) graphic in the speedometer of the instrument cluster.
Operation of the supplemental restraint system (SRS) warning indicator is controlled by a high speed controller area network (CAN) bus message from the restraints control module (RCM) to the instrument cluster. The restraints control module (RCM) illuminates the supplemental restraint system (SRS) warning indicator if a fault is detected, and for approximately 6 seconds during the bulb check at the beginning of each ignition cycle.
