DESCRIPTION





The Occupant Restraint Controller (ORC) is also sometimes referred to as the Airbag Control Module (ORC). The ORC is concealed underneath the instrument panel, beneath the center stack area, just behind the HVAC control and radio. It is secured by three screws to the top of the transmission tunnel. Concealed within the aluminum ORC housing is the electronic circuitry of the ORC which includes a microprocessor, an electronic impact sensor, an electronic safing sensor, and an energy storage capacitor. A stamped metal cover plate is secured to the bottom of the ORC housing with three screws to enclose and protect the internal electronic circuitry and components. This is not to be removed for any reason and service to the ORC is not to be attempted.

An arrow printed on the label on the top of the ORC housing provides a visual verification of the proper orientation of the unit, and should always be pointed toward the front of the vehicle. Two molded plastic electrical connector receptacles exit the rearward facing side of the ORC housing. These two receptacles connect the ORC to the vehicle electrical system.

The impact sensor and safing sensor internal to the ORC are calibrated for the specific vehicle, and are only serviced as a unit with the ORC. The ORC cannot be repaired or adjusted and, if damaged or faulty, must be replaced. For diagnosis and testing, use a scan tool and refer to the appropriate diagnostic information.
