Occupant Restraint Controller - Installation



MODULE, Occupant Restraint Controller

INSTALLATION

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. Carefully position the Occupant Restraint Controller (ORC) bracket (4) and the ORC (1) onto the weld stud (5) at the right front corner of the ORC mount on the floor panel transmission tunnel. When the ORC is correctly positioned, the orientation arrow on the ORC label will be pointed forward in the vehicle.
2. Loosely install the nut (3) that secures the ORC and the ORC bracket to the weld stud on the ORC mount.
3. Align the mounting holes on the left side of the ORC and the ORC bracket with the weld nuts at the left front and rear of the ORC mount.
4. Install and tighten the two screws (2) that secure the ORC and the ORC bracket to the weld nuts of the ORC mount. Tighten the screws to 7 N.m (62 in. lbs.).
5. Tighten the nut that secures the ORC and the ORC bracket to the weld stud of the ORC mount. Tighten the nut to 7 N.m (62 in. lbs.).
6. Reconnect the instrument panel and body wire harness connectors (6) to the ORC connector receptacles located on the rearward facing side of the module. Be certain that the latches on both connectors are each fully engaged.
7. Reinstall the center console onto the top of the floor panel transmission tunnel.
8. Do not reconnect the negative cable to the battery at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component.
