U0002-CAN C BUS OFF PERFORMANCE

For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation
When powered, the Occupant Restraint Controller module (ORC) "listens" to the serial data bus for the broadcast of various serial data messages.
- 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 five 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.
