Occupant Restraint Controller - Removal
REMOVAL
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 airbags in the event of a vehicle rollover event. If an ORC is accidentally rolled during service while still connected to battery power, the side curtain airbags 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.
WARNING: Disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, Occupant Classification System (OCS), seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to follow these instructions may result in accidental airbag deployment and possible serious or fatal injury.
WARNING: 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 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.
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 System (SRS) verification test before replacing the other. Supplemental Restraints Verification Test 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. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Remove the center console from the top of the floor panel transmission tunnel. Floor Console - Removal.
CAUTION: Use care when disengaging the Occupant Restraint Controller (ORC) cover latches from the ORC or the cover may be damaged.
3. The ORC cover (1) is secured to the ORC (4) by a latch tab located on each side of the cover. Gently pry both latch tabs away from the ORC far enough to disengage the latches from the slots in the base of the ORC housing, then lift the cover off of the ORC.
4. Disconnect the two wire harness connectors (3) (one each from the instrument panel and the body wire harnesses) from the ORC connector receptacles located on the forward-facing 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.
5. Remove the three screws (2) that secure the ORC to the ORC bracket (5) that is welded onto the top of the floor panel transmission tunnel.
6. Remove the ORC from the floor panel transmission tunnel.
