Module-Occupant Restraint Controller: Removal

WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, occupant classification system, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment.
WARNING: To avoid personal injury or death, never strike or drop the occupant restraint controller, as it can damage the impact sensor or affect its calibration. The occupant restraint controller contains the impact sensor, which enables the system to deploy the supplemental restraints. If an occupant restraint controller is accidentally dropped during service, the module must be scrapped and replaced with a new unit. Failure to observe this warning could result in accidental, incomplete, or improper supplemental restraint deployment.
CAUTION: 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 one. Then perform SUPPLEMENTAL RESTRAINTS VERIFICATION TEST  before replacing the other. Both the ORC and the OCM store OCS calibration data, which they transfer to one another when one of them is replaced. If both are replaced at the same time, an irreversible fault will be set in both modules.
NOTE: Two different Occupant Restraint Controllers (ORC) are available for this vehicle. For vehicles equipped with the optional side curtain airbags, both ORC connector receptacles are black in color and the ORC contains a second bi-directional safing sensor for the side airbags. For vehicles not equipped with the optional side curtain airbags, the ORC connector receptacles are gray.

  1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
  2. Remove the center console from the top of the floor panel transmission tunnel (1). (Refer to BODY/INTERIOR/FLOOR CONSOLE - REMOVAL) .
  3. Disconnect the instrument panel (3) and body (4) wire harness connectors from the Occupant Restraint Controller (ORC) (4) connector receptacles located on the forward facing side of the module. To disconnect the connectors from the ORC:
    1. Slide the red Connector Position Assurance (CPA) lock on the top of the connector toward the front of the vehicle.
    2. Depress the edge of the CPA lock closest to the ORC to release the connector latch tab and pull the connector straight away from the ORC connector receptacle.

  5. Remove the ORC from the ORC mount.
