Module, Occupant Restraint Controller: Installation: Installation
To avoid serious or fatal injury on vehicles equipped with side curtain or seat airbags, disable the Supplemental Restraint System (SRS) before attempting any Occupant Restraint Controller (ORC) diagnosis or service. The ORC contains a rollover sensor, which enables the system to deploy the side curtain and seat airbags in the event of a vehicle rollover event. If an ORC is accidentally rolled during service while still connected to battery power, the side curtain and seat airbags 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, 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.
Several different Occupant Restraint Controllers (ORC) are available for this vehicle. For vehicles equipped with the optional side curtain or seat airbags the ORC contains a second bi-directional safing sensor.
- Pull the carpet back on each side of the floor panel transmission tunnel below the center of the instrument panel and carefully position the Occupant Restraint Controller (ORC) (3) onto the three studs (1) of the ORC mount on the floor panel transmission tunnel (5).NOTE:
The bottom of the ORC housing is keyed. When the ORC is correctly positioned, the bottom of the housing will fit flush with the mount and the orientation arrow on the label on top of the housing will be pointed forward in the vehicle.
- Install the three nuts (2) that secure the ORC to the studs of the ORC mount. Tighten the nuts to 9 N.m (80 in. lbs.).
- Connect the two instrument panel wire harness connectors (4) to the ORC. Be certain that the latches on the connectors are each fully engaged.
- Do not connect 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 .
