Occupant Restraint Controller - Removal
MODULE, Occupant Restraint Controller
REMOVAL
WARNING:
- To avoid serious or fatal injury on vehicles equipped with side curtain airbags, disable the Supplemental Restraint System (SRS) before attempting any Occupant Restraint Controller (ORC) diagnosis or service. The ORC contains a rollover sensor, which enables the system to deploy the side SRS components in the event of a vehicle rollover event. If an ORC is accidentally rolled during service while still connected to battery power, the side SRS components will deploy. 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 SRS. Failure to take the proper precautions could result in accidental airbag deployment.
- To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, 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 SRS. Failure to take the proper precautions could result in accidental airbag deployment.
- To avoid serious or fatal injury, never strike or drop the Occupant Restraint Controller (ORC), as it can damage the impact sensor or affect its calibration. The ORC contains the impact sensor, which enables the system to deploy the Supplemental Restraint System (SRS) components. If an ORC 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 SRS component deployment.
1. Disconnect and isolate the negative cable from the battery. 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.
3. Disconnect the instrument panel and body wire harness connectors (6) from the Occupant Restraint Controller (ORC) (1) connector receptacles located on the rearward facing side of the module. To disconnect the wire harness connectors from the ORC, depress the release tab and lift the lever arm to the fully open position on each connector. Disconnecting the smaller connector first will allow easier access for disconnecting the large connector.
4. Remove the two screws (2) that secure the ORC to the two weld nuts on the ORC mount welded onto the top of the floor panel transmission tunnel.
5. Remove the nut (3) that secures the ORC and the ORC bracket (4) to the weld stud (5) on the ORC mount.
6. Remove the ORC and the ORC bracket from the ORC mount.
