Module, Occupant Restraint Controller: Removal
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbags, airbag curtains, knee blocker, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect the Intelligent Battery Sensor (IBS)/negative battery cable assembly from the negative battery post, 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.
Several different Occupant Restraint Controllers (ORC) are available for this vehicle. For vehicles equipped with the optional seat-mounted side airbags the ORC contains a second bi-directional safing sensor.
- Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable. Wait two minutes for the system capacitor to discharge before further service.
- Remove the center console from the top of the floor panel transmission tunnel. Refer to CONSOLE, CENTER, REMOVAL .
- Unlatch and disconnect the instrument panel wire harness (4) and body wire harness (3) connectors (2) from the Occupant Restraint Controller (ORC) (1) connector receptacles located on the right side of the module. To disconnect the wire harness connectors from the ORC, depress the release tab and lift the lever arm on each connector.
- Remove the four nuts (1) that secure the ORC (2) to the three studs on the ORC mount (3) welded onto the top of the floor panel transmission tunnel.
- Remove the ORC from the ORC mount.
