AIR BAG Telltale Indicator Lamp

The AIR BAG telltale indicator lamp is powered by ignition voltage and grounded by the SIR Lamp Driver Module. The SDM controls the lamp by providing a signal to the lamp driver. The lamp driver module uses the SDM signal to determine when to provide a ground for the AIR BAG telltale. The AIR BAG telltale indicator lamp is used in the SIR system to notify the vehicle's operator of the following:
1. Correct system operation by flashing seven times when the ignition switch is first turned On and then turned Off.
2. To warn the operator of the vehicle of SIR electrical system malfunctions which could potentially affect the operation of the SIR system.

The AIR BAG telltale indicator lamp is the key to driver notification of SIR system malfunctions. For proper operation, refer to SIR Diagnostic System Check in Air Bags (Supplemental Restraint Systems). Air Bag Systems
