Module, Occupant Restraint Controller: Installation
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 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.
- Carefully position the ORC (3) onto the weld studs on the top of the floor panel. When the ORC is correctly positioned, the bottom of the housing will fit flush with the floor and the orientation arrow on the label on top of the housing will be pointed forward in the vehicle.
- Install and tighten the three nuts (1) that secure the ORC to the weld studs on the top of the floor panel. Tighten the nuts to 8 N. m (71 in. lbs.).
- Connect both the instrument panel and the body wire harness connectors (2) to the right side of the ORC. Be certain that the latch on each connector is fully engaged.
- Restore the floor carpet (4) into position over the top of the ORC.
- Install the lower trim and the fasteners and tighten securely.
- Install the fasteners (1) securing the cup holder trim support bracket (2) to the instrument panel and tighten securely.
- Install the instrument panel cupholder. Refer to CUPHOLDER, INSTRUMENT PANEL, INSTALLATION .
- If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to align the PROXI configuration data into the new ECU. Follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under Body Control Module (BCM) Miscellaneous Functions menu.
- Do not connect the negative battery cable at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. Refer to STANDARD PROCEDURE .
