Decoding U0004: Understanding The Cause Of Your Car’s Communication Failure
The U0004 fault code is related to the High Speed CAN Communication Bus (+) Low. The Controller Area Network (CAN) is a vehicle bus standard designed to interconnect automotive devices without a host computer.
CAN bus uses two dedicated wires for communication, CAN high and CAN low. The U0004 code sets when a supervised periodic message that includes the transmitter device availability has not been received. This fault code indicates a problem with the communication between the devices on the CAN bus.
The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise, but a fault in the communication can cause issues with the vehicle’s performance. It is important to diagnose and fix the issue causing the U0004 fault code to ensure proper communication between the devices on the CAN bus.
