Controller, Occupant Restraint: Removal: Module
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.
- Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
- Remove the protective cover from the Occupant Restraint Controller (ORC) (1). Refer to CONTROLLER, OCCUPANT RESTRAINT, REMOVAL .
- Disconnect the instrument panel and body wire harness connectors (3) for the ORC from the ORC connector receptacles (2 and 4) located on the forward facing side of the module. To disconnect the connectors from the ORC:
- Slide the red Connector Position Assurance (CPA) lock on the top of the connector to the side.
- 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.
- Remove the three nuts (2) that secure the ORC (1) to the studs of the ORC mount (3) welded onto the top of the floor panel transmission tunnel.
- Remove the ORC from the ORC mount.
