Decoding U0018: Understanding The Vehicle Communication Network
The U0018 code is related to the Controller Area Network (CAN) in a vehicle. CAN is a bus standard that connects automotive devices without a host computer.
CAN bus uses two wires for communication, CAN high and CAN low.
The U0018 code sets when the Medium Speed CAN Communication Bus (-) is shorted to Bus (+). This fault code indicates that a supervised periodic message has not been received. The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise.
