Controller-Occupant Restraint
WARNING:
On vehicles equipped with the Occupant Classification System (OCS), never replace both the Occupant Restraint Controller (ORC) and the Occupant Classification Module (OCM) at the same time. If both require replacement, replace the OCM first. Then perform the Airbag System test. See DIAGNOSIS AND TESTING including an ignition-On time of at least one minute before replacing the ORC. Both the ORC and the OCM store OCS calibration data, which they transfer to one another during the first minute of ignition-On time after one of them is replaced. If both modules are replaced at the same time, an irreversible fault will be set in both modules.
- Open hood, disconnect and isolate the battery negative cable.WARNING: Wait two minutes for the airbag system reserve capacitor to discharge before beginning any airbag system or component service. Failure to do so may result in accidental airbag deployment, personal injury or death.
- Remove the left and right forward console closeout panels (1).
- From the right side of the vehicle, disconnect the two ORC electrical connectors (2 and 3, referred to as C1 and C2 in the diagnostic information and wiring).
- Remove the three retaining screws (2) to the ORC (1). One on the left side of the floor tunnel, and one in front of (toward bulkhead) and behind (toward vehicle rear) the ORC unit.
- Remove ORC (1) from vehicle.
