Air bag system is monitored by Occupant Restraint Controller (ORC). ORC contains safing sensor, an integral sensor in circuitry of system, which is used to deploy air bag modules.
ORC monitors critical input and output circuits within air bag system, ensuring they operate correctly. Some circuits are tested continuously; others are checked under certain conditions. ORC provides information about air bag system through AIR BAG warning light and DRBIII. Each circuit monitored by ORC has a corresponding Diagnostic Trouble Code (DTC) assigned to it.
