Service Procedure

1. Disconnect and isolate the negative battery (ground) cable. Then wait two minutes for the system capacitor to discharge before continuing. This is the only sure way to disable the supplemental restraint system.

WARNING:
Failure to take proper precautions (disconnecting the negative battery cable) could result in accidental airbag deployment and/or personal injury or death.

NOTE:
To enhance customer satisfaction, remember to reset the clock when you have completed the service procedure.

2. Remove the center console from the top of the floor panel transmission tunnel.

3. Disconnect the two body wiring harness connectors from the ORC connector receptacles located on the forward facing side of the controller.

NOTE:
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 that secure the ORC to the ORC mounting bracket.

5. Remove and discard the original ORC.

6. Carefully position the ORC onto the ORC mounting bracket. 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 mounting bracket.

WARNING:
If the new ORC is accidentally dropped during service, the controller must be scrapped and replaced with a new unit. Failure to observe this warning could result in accidental, incomplete, or improper supplemental restraint deployment.

7. Install the three screws that secure the ORC to the ORC mounting bracket.
Tighten the screws to 96 in. lbs. (11 N.m).

8. With the connectors in the unlatched position, reconnect the two body wire harness connectors to the ORC connector receptacles located on the forward facing side of the controller.

9. Latch the two connectors to the ORC.

10. Install the center console from the top of the floor panel transmission tunnel.

11. Using the following procedure, perform the ORC Verification Test:

a. Turn the ignition key to the "RUN" position and then reconnect the battery.

b. Connect the StarSCAN scan tool to the data link connector.

NOTE:
The StarSCAN must be at the most current software level available.

c. Using the StarSCAN scan tool, erase any stored Diagnostic Trouble Codes (DTC's) in all airbag modules.

d. Turn the ignition to the "OFF" position and wait 15 seconds.

e. Turn the ignition to the "ON" position.

f. Wait one minute and then read active and stored DTC's.

NOTE:
If equipped with an Airbag On/Off switch, read the DTC's in all switch positions.

> If there are no active or stored DTC's present the repair is complete.

> If there are active or stored DTC's present use the standard repair procedure for that particular DTC.

12. Disconnect the StarSCAN scan tool from the vehicle.
