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) and bracket onto the weld studs of the ORC mount located on the floor panel transmission tunnel. When the ORC is correctly positioned, the orientation arrow on the ORC label will be pointing toward the front of the vehicle.
- Loosely install the nuts (2) securing the ORC and bracket to the weld studs on the ORC mount.
- Tighten the nuts to the proper specifications. Refer to TORQUE SPECIFICATIONS .
- Connect the instrument panel and body wire harness connectors (1) to the ORC, located on the rearward facing side of the ORC. Make sure the latches on both connectors are each fully engaged.
- Install the center floor console. Refer to CONSOLE, FLOOR, INSTALLATION .
- Do not connect the negative battery cable at this time. The Supplemental Restraint System (SRS) Verification Test procedure must be performed anytime a SRS component is serviced. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST
.NOTE:
If a new ORC was installed, or the ORC software has been updated, the Electronic Stability Control (ESC) system will require re-initialization, using a diagnostic scan tool. Refer to the appropriate diagnostic procedures.
