U0184: Understanding The Mysterious Lost Communication With Radio Code

The U0184 code is a Controller Area Network (CAN) fault code.

CAN is a vehicle bus standard designed to interconnect automotive devices without a host computer.

The code sets when a periodic message from the Radio Unit has not been received.

CAN bus uses two dedicated wires for communication, CAN high and CAN low.

The Diagnostic Trouble Code (DTC) sets when there is a loss of communication with the Radio Unit.

The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise.
