Module, Occupant Restraint Control (Orc): 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 may contain a rollover sensor, which enables the system to deploy the side SRS components in the event of a vehicle rollover event. If an ORC containing a rollover sensor is accidentally rolled during service while still connected to battery power, the side SRS components 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 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. Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable. Wait two minutes for the system capacitor to discharge before continuing service.
  2. Remove the front side panels from the center floor console on both the right and left sides of the floor panel transmission tunnel. Refer to CONSOLE, FLOOR, REMOVAL .

  3. Working from the left side front floor panel, reach around the forward edge of the instrument panel center stack support on the floor panel transmission tunnel (5) to access, unlatch and disconnect the wire harness connector (4) from the ORC (2) connector. To disconnect the wire harness connector from the ORC, press the release tab and lift the lever arm on the connector.
  4. Still working from the left side front floor panel, remove the fasteners (1) that secures the left front mount of the ORC to the stud on the top of the floor panel transmission tunnel.
  5. Working from the right side front floor panel, remove the bracket that secures the lower instrument panel center stack structural support to the floor panel transmission tunnel. Refer to PANEL, INSTRUMENT, REMOVAL .
  6. Still working from the right side front floor panel, reach around the forward edge of the instrument panel center stack support to access, unlatch and disconnect the instrument panel wire harness connector (3) from the ORC connector receptacle located on the rearward facing side of the module. To disconnect the wire harness connector from the ORC, press the release tab and lift the lever arm on the connector.
  7. Still on the right side, remove the fasteners (1) that secure the right front and rear mounts of the ORC to the studs on the top of the floor panel transmission tunnel.
  8. Remove the ORC from the vehicle.
