Occupant Restraint Controller (ORC)
U0002-00-CAN C BUS OFF PERFORMANCE
For a complete wiring diagram Refer to the Wiring Information.
- When Monitored:
The ORC checks for serial data message traffic at power up during the initialization process, and continuously through the ignition cycle.
- Set Condition:
This DTC sets when the ORC fails to detect serial data message traffic for more than 5 seconds. In the event the ORC detects serial data message traffic, this DTC will immediately transition to stored status.
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.
1. DETERMINE ACTIVE OR STORED DTC
Is the DTC active or stored?
ORC - ACTIVE DTC
- Go To 2
ORC - STORED DTC

3. STORED ORC DTC
1. With the scan tool, record and erase all DTC's from all Airbag System Modules.
2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.

8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
9. If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
10. If only stored codes return continue the test until the problem area has been isolated.
11. In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.
