Seat Occupant Classification Module - Air Bag: Service and Repair
Occupant Restraint Controller (ORC) Module - Installation
INSTALLATION
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 contains a rollover sensor, which enables the
system to deploy the side curtains 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 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.
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, 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.
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.
NOTE: Several different Occupant Restraint Controllers (ORC) are available for this vehicle. For vehicles equipped with the optional side
curtain airbags, the ORC contains a second bi-directional safing sensor for the side airbags.
1. Carefully position the Occupant Restraint Controller (ORC) (3) onto the ORC mount on the floor panel transmission tunnel (1). 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.
2. Install and tighten the three screws (2) that secure the ORC to the ORC mount that is welded onto the floor panel transmission tunnel. Tighten the
screws to 14 Nm (10 ft. lbs.).
