The U0045 code is related to the Controller Area Network (CAN) bus system in a vehicle.

The CAN bus is a standard designed to connect automotive devices without a host computer. It uses two dedicated wires for communication, CAN high and CAN low.

The U0045 code sets when the vehicle communication bus ‘B’ (-) is shorted to bus ‘B’ (+).

This means that there is a problem with the communication between the devices on the CAN bus.

The Diagnostic Trouble Code (DTC) sets when a supervised periodic message that includes the transmitter device availability has not been received. The U0045 code indicates that there is a short circuit between the two bus lines, which can cause communication issues between the devices on the CAN bus.
