The u0037 fault code is related to the Vehicle Communication Bus ‘B’. It is a Controller Area Network (CAN) bus standard designed to interconnect automotive devices without a host computer.

The CAN bus uses two dedicated wires for communication, CAN high and CAN low. When the CAN bus is in idle mode, both lines carry 2.5V.

The Diagnostic Trouble Code (DTC) sets when a supervised periodic message that includes the transmitter device availability has not been received.

The u0037 code indicates that there is a communication problem on the Vehicle Communication Bus ‘B’.
