Occupant Restraint Controller/Air Bag Control Module (Orc/ACM)

WARNING: This page is about a different car, the 2000 Dodge Intrepid, 2000 Chrysler LHS, 2000 Chrysler Intrepid, 2000 Chrysler Concorde, and 2000 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

The ORC/ACM is mounted on bracket on transmission tunnel below instrument panel. The ORC/ACM mounting bracket also serves as instrument panel center support.

The ORC/ACM contains a microprocessor, impact sensor and energy- storage capacitors. The microprocessor contains the air bag system logic. The air bag system logic includes On-Board Diagnostics (OBD) and capability to communicate with instrument cluster to control the AIR BAG warning light. The microprocessor ORC/ACM monitors impact sensor signal and air bag system electrical circuits to determine system readiness. If ORC/ACM detects system fault, it sends message to Mechanical Instrument Cluster (MIC) to turn on the AIR BAG warning light. The ORC/ACM microprocessor is pre-programmed to determine when deceleration rate is severe enough to require air bag system protection. When programmed conditions are met, ORC/ACM sends an electrical signal to deploy air bag system components.
