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 SRS components in the event of a vehicle rollover event. If an ORC 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.
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.
1. Working from the right side of the floor panel transmission tunnel, carefully position the Occupant Restraint Controller (ORC) (1) to the ORC
mounting bracket (3) welded onto the top of the floor panel transmission tunnel. When the ORC is correctly positioned, the arrow on the ORC
label will be pointed forward in the vehicle and the locating pins on the bottom of the ORC will be engaged into the locating holes in the bracket.
2. Install and tighten the three screws (2) that secure the ORC to the ORC mounting bracket. Tighten the screws to 10 Nm (88 in. lbs.).
CAUTION: The lever arms of the wire harness connectors for the ORC MUST be in the unlatched position before they are inserted into
their connector receptacles on the ORC or they may become damaged.
NOTE: Service ORC modules are shipped in a "Locked Out" state and when replaced, will set a B-2722 fault code, ORC UNLOCKED-ALL
DEPLOYMENT DISABLED. Utilize the diagnostic Scan Tool and access the ORC module and go into the MISCELLANEOUS menu and
perform the MODULE INITIALIZATION procedure and then erase the fault codes.
3. Reconnect the body wire harness connector (5) and the instrument panel wire harness connector (4) 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.
4. Reinstall the Electronic Stability Program (ESP) dynamics sensor onto the right side of the ORC mounting bracket.See: Brakes and Traction
Control/Antilock Brakes / Traction Control Systems/Lateral Accelerometer/Service and Repair/Installation.
5. Do not reconnect the battery negative cable at this time. The Supplemental Restraint System (SRS) verification test procedure should be performed
following service of any SRS component.See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Diagnostic
Trouble Code Tests and Associated Procedures/Verification Tests.
