The U0053 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. The U0053 code indicates a problem with the communication bus ‘C’ (-) high.

This means that the voltage differential between the CAN high and CAN low lines is not within the expected range. The code sets when a supervised periodic message that includes the transmitter device availability has not been received. The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise, but a problem with the communication bus can cause issues with various vehicle systems.
