Module, Occupant Restraint Controller: Installation: 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, 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.
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) (2) onto the front of the floor panel transmission tunnel (5), aligning the mounts of the ORC to the studs on 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.
- Working from the passenger side front floor panel, reach around the forward edge of the instrument panel center stack support on the floor panel transmission tunnel to install and tighten the two nuts (1) that secure the ORC to the studs on the floor panel transmission tunnel. Tighten the nuts to 8 N.m (71 in. lbs.).
- Still on the passenger side, reconnect and latch the instrument panel wire harness connector (3) to the ORC connector receptacle located on the rearward facing side of the module. Be certain that the latch on the connector is fully engaged.
- Working from the driver side front floor panel, reach around the forward edge of the instrument panel center stack support on the floor panel transmission tunnel to install and tighten the nut (1) that secures the ORC to the stud on the floor panel transmission tunnel. Tighten the nut to 8 N.m (71 in. lbs.).
- Still on the driver side, reconnect and latch the body wire harness connector (4) to the ORC connector receptacle located on the rearward facing side of the module. Be certain that the latch on the connector is fully engaged.
- Reinstall the front side panels onto the center floor console on both the right and left sides of the floor panel transmission tunnel. Refer to CONSOLE, FLOOR, 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.
- If this Electronic Control Unit (ECU) is being replaced with a new unit, the Initialize ORC Miscellaneous Function must be run using a diagnostic scan tool.
- Do not reconnect the negative cable to the battery at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. Refer to STANDARD PROCEDURE .
