Occupant Restraint Controller - Installation
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 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: 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, Occupant Classification System (OCS), 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 follow these instructions may result in accidental airbag deployment.
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. Carefully position the Occupant Restraint Controller (ORC) (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 locating pin on the bottom of the right ORC mounting flange will be engaged into the locating hole in the ORC bracket (5).
2. Install and tighten the three screws (2) that secure the ORC to the ORC bracket that is welded onto the floor panel transmission tunnel. Tighten the screws to 10.5 Nm (95 in. lbs.).
CAUTION: The lever arms of the wire harness connectors for the ORC MUST be in the unlatched position before they are inserted into their connector receptacles on the ORC or they may become damaged.
3. Reconnect the two wire harness connectors (3) (one each from the instrument panel and the body wire harnesses) for the ORC to the ORC connector receptacles located on the forward facing side of the module. Be certain that the latches on both connectors are each fully engaged.
4. Carefully position the ORC cover (1) back over the top of the ORC. Be certain both cover latches are engaged in the slots in the base of the ORC housing.
5. Reinstall the center console onto the top of the floor panel transmission tunnel. Floor Console - Installation.
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. Service and Repair.
