The U0014 code is related to the Medium Speed CAN Communication Bus (+) High. It is a Diagnostic Trouble Code (DTC) that sets when a supervised periodic message is not received. 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 U0014 code indicates a problem with the CAN high line, which is responsible for transmitting data bits.

The code means that the voltage differential between the two bus lines is not within the expected range, which can cause communication issues between devices.
