Occupant Restraint Controller - Installation



MODULE, Occupant Restraint Controller

INSTALLATION

WARNING:
- 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) (1) to the ORC bracket (3) that is welded onto the top of the floor panel transmission tunnel (3) below the instrument panel. When the ORC is correctly positioned, the arrow on the ORC label will be pointed forward in the vehicle and the locating pins on the bottom of the ORC will be engaged into the locating holes in the ORC bracket.
2. Install and tighten the three screws (2) that secure the ORC to the ORC bracket. Tighten the screws to 11 N.m (8 ft. lbs.).







3. Restore the sound deadening material (1) over and around the ORC.







4. First reconnect the body wire harness connector (1), followed by the instrument panel wire harness connector (2) 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.
5. Reinstall the floor console onto the top of the floor panel transmission tunnel.
6. Do not reconnect the battery negative cable at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component.
