The U0007 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 U0007 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 this fault code can occur due to a wiring issue or a faulty device on the bus. A professional diagnosis is required to determine the exact cause of the U0007 fault code.
