Occupant Restraint Controller

MODULE

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, 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 OCCUPANT RESTRAINT CONTROLLER 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.


REMOVAL




1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Remove the protective cover from the Occupant Restraint Controller (ORC) (1).
3. Unlatch and disconnect the two wire harness connectors for the ORC from the ORC connector receptacles (2 & 4) 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 nuts (2) that secure the ORC (1) to the studs on the ORC mounting bracket (3) on the floor panel transmission tunnel.
5. Remove the ORC from the floor panel transmission tunnel.

INSTALLATION




1. Position the Occupant Restraint Controller (ORC) (1) over the three studs of the ORC mounting bracket (3) on the floor panel transmission tunnel, then engage the locating pin on the bottom of the right ORC mounting flange into the locating hole in the bracket. When the ORC is correctly positioned, the arrow on the ORC label will be pointed forward in the vehicle.
2. Install and tighten the three nuts (2) that secure the ORC to the bracket on the floor panel transmission tunnel. Tighten the nuts to 10 N.m (7 ft. lbs.).




3. Reconnect the two wire harness connectors (3) for the ORC (1) to the ORC connector receptacles (2 & 4) located on the forward facing side of the module. Be certain that the latches on the connectors are each fully engaged.
4. Reinstall the ORC cover onto the ORC.
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.

REMOVAL




1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.

NOTE: The front seat assembly must be unfastened from the floor panel, but need not be removed from the vehicle for access to the Occupant Restraint Controller (ORC) cover for service.

2. Remove the front seat from the vehicle.
3. Using a trim stick or another suitable wide flat-bladed tool, gently pry the latch feature on either side of the ORC cover (1) away from the base of the ORC (2) far enough to disengage the cover from the module.
4. Remove the ORC cover from over the ORC.

INSTALLATION




1. Position the ORC cover (1) over the Occupant Restraint Controller (ORC) (2).
2. Align the latch feature on each side of the ORC cover with the notch in each side at the base of the ORC housing.
3. Using hand pressure, press firmly and evenly downward on the ORC cover until each latch feature is fully engaged with the ORC housing.
4. Reinstall the front seat into the vehicle.
5. Reconnect the battery negative cable.
