Occupant Restraint Controller

WARNING:
- TO AVOID PERSONAL INJURY OR DEATH, ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, AIRBAG, OCCUPANT CLASSIFICATION SYSTEM, 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 SUPPLEMENTAL RESTRAINT SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT.
- TO AVOID PERSONAL INJURY OR DEATH, NEVER STRIKE OR DROP THE OCCUPANT RESTRAINT CONTROLLER, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. THE OCCUPANT RESTRAINT CONTROLLER CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE SUPPLEMENTAL RESTRAINTS. IF AN AIRBAG CONTROL MODULE 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 SUPPLEMENTAL RESTRAINT 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 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.

REMOVAL




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.
3. Disconnect the two body wire harness connectors
1. from the Occupant Restraint Controller (ORC)
2. 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 three screws (3) that secure the ORC to the ORC bracket (4) that is welded onto the top of the floor panel transmission tunnel.
5. Remove the ORC from the floor panel transmission tunnel.

INSTALLATION




1. Carefully position the Occupant Restraint Controller (ORC) (2) to the ORC bracket (4) on 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 pin on the bottom of the right ORC mounting flange will be engaged into the locating hole in the ORC bracket.
2. Install and tighten the three screws (3) that secure the ORC to the ORC bracket that is welded onto the floor panel transmission tunnel. Tighten the screws to 11 Nm (8 ft. 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.

3. Reconnect the two body wire harness connectors (1) to the ORC connector receptacles located on the forward facing side of the module. Be certain that the latches on both connectors are each fully engaged.
4. Reinstall the center console onto the top of the floor panel transmission tunnel.
5. Do not reconnect the battery negative cable at this time. The supplemental restraint system verification test procedure should be performed following service of any supplemental restraint system component.
