WARNING: This page is about a different car, the 1995 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
SRS is monitored by Air Bag System Diagnostic Module (ASDM). ASDM contains safing sensor, an integral sensor in circuitry of system, which is used to fire air bag module.
ASDM monitors critical input and output circuits within air bag system, ensuring they are operating correctly. Some circuits are tested continuously, and others are checked under certain circumstances. ASDM provides information about air bag system through AIR BAG warning light and DRB. Each circuit monitored by ASDM has a corresponding fault code (message) assigned to it. For a description of fault codes, see DIAGNOSTIC FAULT CODES (MESSAGES) .
