Module - Occupant Restraint Controller: Installation

WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, occupant classification system, 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 supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment.

WARNING: To avoid personal injury or death, never strike or drop the occupant restraint controller, as it can damage the impact sensor or affect its calibration. The occupant restraint controller contains the impact sensor, which enables the system to deploy the supplemental restraints. If an occupant restraint controller 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 supplemental restraint deployment.

CAUTION: On vehicles equipped with the Occupant Classification System (OCS), never replace both the Occupant Restraint Controller (ORC) and the Occupant Classification Module (OCM) at the same time. If both require replacement, replace one. Then perform the supplemental restraint verification test before replacing the other. Both the ORC and the OCM store OCS calibration data, which they transfer to one another when one of them is replaced. If both are replaced at the same time, an irreversible fault will be set in both modules.

1. Carefully position the Occupant Restraint Controller (ORC) (1) onto the studs of the ORC mount (4) on the floor panel transmission tunnel. When the ORC is correctly positioned, the arrow on the ORC label will be pointed forward in the vehicle and the ORC connector receptacles will be facing the left side of the vehicle.
2. Install and tighten the three nuts (2) that secure the ORC to the studs of the ORC mount that is welded onto the floor panel transmission tunnel. Tighten the nuts to 6 N.m (50 in. lbs.).
3. Reinstall the floor distribution duct onto the bottom of the heater-air conditioner housing. (Refer to INSTALLATION ).
4. Reinstall the instrument panel into the vehicle. (Refer to INSTALLATION ).

5. Reconnect the instrument panel (1) and body (3) wire harness connectors to the ORC (2) connector receptacles located on the left facing side of the module. Be certain that the latches and the red CPA locks on both connectors are each fully engaged.
6. Do not reconnect the battery negative cable at this time. The supplemental restraint system verification test procedure should be performed following service of any supplemental restraint system component. (Refer to SUPPLEMENTAL RESTRAINTS VERIFICATION TEST ).
