Air Bag Warning Light
WARNING: This page is about a different car, the 2002 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
Whenever ignition switch is in RUN or START position, AIR BAG warning light on instrument panel will illuminate for 6-8 seconds and then turn off. This signifies Air Bag Control Module (ACM) has checked the air bag system and found it functioning properly. If AIR BAG warning light illuminates for 12 seconds or more, stays on all the time or does not come on, an air bag system malfunction exists, and Diagnostic Trouble Code (DTC) will be stored in ACM memory.
