Circuit Description
WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue. However, it is still accessible from the selected car via links, so may be relevant.
When ignition is turned on, Instrument Panel Cluster (IPC) flashes AIR BAG warning light 7 times. Sensing and Diagnostic Module (SDM) performs diagnostic tests on SIR system during this time. If SIR system checks okay, SDM commands IPC to turn off AIR BAG warning light.
