Air Bag Warning Light
WARNING: This page is about a different car, the 2002 Buick Park Avenue. However, it is still accessible from the selected car via links, so may be relevant.
When ignition is turned on, Sensing and Diagnostic Module (SDM) is supplied with ignition voltage. SDM requests Instrument Panel Cluster (IPC) to flash AIR BAG warning light 7 times while SDM verifies air bag system operation. If system is okay, AIR BAG warning light will turn off. During vehicle operation, AIR BAG warning light warns driver of malfunctions which could potentially affect SIR system operation.
