Commander 4WD V8-4.7L Flex Fuel (2009)
Air Bag Control Module: Service and Repair
Occupant Restraint Controller - Removal
REMOVAL
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. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Remove the center console from the top of the floor panel transmission tunnel (1). See: Body and Frame/Interior Moulding / Trim/Console/Service
and Repair/Floor Console - Removal.
3. Disconnect the instrument panel (3) (C2) and body (4) (C1) wire harness connectors from the Occupant Restraint Controller (ORC) (2) connector
receptacles located on the forward facing side of the module. To disconnect the connectors from the ORC:
a. Slide the red Connector Position Assurance (CPA) lock on the top of the connector toward the front of the vehicle.
b. Depress the edge of the CPA lock closest to the ORC to release the connector latch tab and pull the connector straight away from the ORC
connector receptacle.
