Occupant Restraint Controller (ORC)

U0001-00-CAN C BUS

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 Diagnostic Trouble Code (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.





VERIFY ACTIVE DTC

NOTE: Make sure the IOD fuse is installed and battery Voltage is between 10 and 16 Volts before proceeding.

1. Turn the ignition on.
2. With the scan tool, read ORC DTCs.

Does the scan tool display active U0001-00-CAN C BUS - DTC?

Yes

- Totally Integrated Power Module (TIPM) and perform the U0001-Can C Bus diagnostic procedure.

No
