Occupant Restraint Controller: Installation
WARNING:
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 the OCM first. Then perform the Airbag System test (Refer to ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TESTING - AIRBAG SYSTEM) including an ignition-On time of at least one minute before replacing the ORC. Both the ORC and the OCM store OCS calibration data, which they transfer to one another during the first minute of ignition-On time after one of them is replaced. If both modules are replaced at the same time, an irreversible fault will be set in both modules.
- Position ORC in vehicle.
- Install the three retaining screws to the ORC. One on the left side of the floor tunnel, and one in front of (toward bulkhead) and behind (toward vehicle rear) the ORC unit. See Figure. Torque screws to 14.5 N.m (128 in. lbs.).
- From the right side of the vehicle, connect the two ORC electrical connectors. See Figure.
- Install the left and right forward console closeout panels. See Figure.WARNING: DO NOT CONNECT THE BATTERY NEGATIVE CABLE. (Refer to ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TESTING - AIRBAG SYSTEM) FIRST. FAILURE TO DO SO COULD RESULT IN OCCUPANT PERSONAL INJURY OR DEATH.
- Verify vehicle and system operation.
- Close hood.
