Module, Occupant Restraint Controller: Installation
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.
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbags, airbag curtains, knee blocker, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect the Intelligent Battery Sensor (IBS)/negative battery cable assembly from the negative battery post, 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 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.
- Carefully position the Occupant Restraint Controller (ORC) bracket and the ORC onto the weld studs on the ORC mount on the floor panel transmission tunnel. When the ORC is correctly positioned, the orientation arrow on the ORC label will be pointed forward in the vehicle.
- Loosely install the nuts (2) that secures the ORC and the ORC bracket to the weld studs on the ORC mount.
- Tighten the nuts that secure the ORC and the ORC bracket to the weld studs of the ORC mount. Tighten the nuts to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .
- Connect the instrument panel and body wire harness connectors (1) to the ORC connector receptacles located on the rearward facing side of the module. Be certain that the latches on both connectors are each fully engaged.
- Install the center console onto the top of the floor panel transmission tunnel. Refer to CONSOLE, FLOOR, INSTALLATION .
- 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 SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .NOTE:
If the ORC is being replaced with a new unit or if the ORC software has been re-flashed, the Electronic Stability Control (ESC) system will require re-initialization using a diagnostic scan tool. Refer to the appropriate diagnostic procedures.
