Air Bag Warning Lamp

The ignition switch applies ignition voltage to the AIR BAG warning lamp. The AIR BAG warning lamp receives power whenever the ignition switch is at the RUN or START positions.The inflatable restraint Sensing And Diagnostic Module (SDM)controls the lamp by providing ground with a lamp driver. The SIR system uses the AIR BAG warning lamp to do the following:
^ Verify lamp and SDM operation by flashing the lamp seven times when the ignition switch is first turned to the RUN position.
^ When lit, alerts the driver of electrical system malfunctions that could affect the operation of the SIR system. Certain malfunctions can result in:
- Deployment of the air bag(s) without a crash
- Non-deployment of the air bag(s) in the event of a crash; or
- Deployment of the air bag(s) for conditions less severe than intended.

The AIR BAG warning lamp is the key to driver notification of SIR system malfunctions. Refer to the Diagnostic System Check SIR for proper lamp operation.
