The Occupant Restraint Controller (ORC) (2) is sometimes referred to as the Airbag Control Module (ACM). The ORC is mounted on the tunnel floor
pan, between the transmission shifter (3) and parking brake (1).
The ORC contains a microprocessor, the impact sensing device, and energy storage capacitors. The microprocessor contains the airbag system logic. The
airbag system logic includes On-Board Diagnostics (OBD) capability, and communicates with the instrument cluster circuitry on the Controller Area
Network (CAN) data bus to control the airbag indicator lamp.
