Liberty 4WD V6-3.7L (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 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 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: 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 negative battery (ground) cable, then wait two minutes for the airbag 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 and possible serious or fatal injury.
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 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.
CAUTION: On vehicles equipped with the Occupant Classification System (OCS), never replace both the Occupant Restraint Controller
(ORC) and the Occupant Classification Module (OCM) at the same time. If both require replacement, replace one. Then perform
the Supplemental Restraint System (SRS) verification test before replacing the other. Both the ORC and the OCM store OCS
calibration data, which they transfer to one another when one of them is replaced. If both are replaced at the same time, an
irreversible fault will be set in both modules. See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Diagnostic Trouble Code Tests and Associated Procedures/Verification Tests/Supplemental Restraints Verification Test
NOTE: The Occupant Restraint Controller (ORC) should only be removed as a complete unit with the molded plastic mounting bracket. The
service replacement ORC is supplied already installed on a new bracket.
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. See: Body and Frame/Interior Moulding / Trim/Console/Service
and Repair/Floor Console - Removal.
3. Unlatch and disconnect the body wire harness connector (5) and the instrument panel wire harness connector (6) from the Occupant Restraint
Controller (ORC) (3) connector receptacles located on the forward-facing side of the module. To disconnect the wire harness connectors from the
ORC, depress the release tab and lift the lever arm on each connector.
4. Remove the two nuts (2) that secure the left side of the ORC mounting bracket to the two studs on the ORC mount (4) welded onto the top of the
floor panel transmission tunnel.
5. Remove the two screws (1) that secure the right side of the ORC mounting bracket to the ORC mount.
6. Remove the ORC and mounting bracket unit from the ORC mount.
