SRS is monitored by Air Bag Control Module (ACM). ACM contains safing sensor, an integral sensor in circuitry of system, which is used to fire air bag modules.

ACM monitors critical input and output circuits within air bag system, ensuring they are operating correctly. Some circuits are tested continuously; others are checked under certain circumstances. ACM provides information about air bag system through AIR BAG warning light and DRB. Each circuit monitored by ACM has a corresponding fault code (message) assigned to it. For a description of fault codes, see DIAGNOSTIC FAULT CODES (MESSAGES).
