Air Bag Indicator

The AIR BAG indicator, located in the IPC, is used to notify the driver of the SIR system malfunctions. When the ignition is turned ON, the SDM is supplied with ignition 1 voltage. The SDM flashes the AIR BAG indicator seven times. While flashing the AIR BAG indicator, the SDM conducts tests on all SIR system components and circuits. If no malfunctions are detected, the SDM will turn the AIR BAG indicator OFF. The SDM provides continuous monitoring of the inflator module and seat belt pretensioner circuits by conducting a sequence of checks. If a malfunction is detected, the SDM will store a Diagnostic Trouble Code (DTC) and turn the AIR BAG indicator ON. The presence of a SIR system malfunction could result in non-deployment of the inflator modules or the seat belt pretensioners. The AIR BAG indicator will remain ON until the malfunction has been repaired.
