U0001 code

Possible causes U0001 code:

- CAN C Bus (+) Circuit shorted to ground

- CAN C Bus (-) circuit shorted to voltage

- CAN C Bus  (+) circuit shorted to CAN C Bus (-) circuit

- Antilock Brake Module (ABS)

- Powertrain Control Module (PCM) - Gas only

- Engine Control Module (ECM) - Diesel only

- Transmission Control Module (TCM)

Diagnostic test U0001 code

Step 1. verify diagnostic trouble code is active

Make sure the IOD fuse is installed and battery voltage is between 10 and 16 volts before proceeding. Turn the ignition on, with the scan tool read the active ORC DTCs.

Does the scan tool display active U0001 code?

Yes, go to step 2.

No, perform the Stored Lost Communication.

Step 2. Verify Occupant Restraint Controller 

Turn the ignition off, disconnect the 12 volts battery and wait two minutes before proceeding. Disconnect the ORC harness connector. Turn the ignition on, then reconnect the 12 volt battery and wait two minutes before proceeding.

With the scan tool, record and erase TIPM DTCs. Cycle the ignition from on to off three times. Turn the ignition on, with the scan tool read the active DTCs in all modules.

Is the U0001 code active in other modules?

Yes, refer to labels this site and see DTC in the Totally Integrated Power Module (TIPM)

No, inspect the wiring and connectors for damage or shorted circuits. If ok, replace the Occupant Restraint Controller (ORC module), perform the Airbag system verification.
