    Controller Area Network, you must test the power supply first
    then test all cables for CAN, see they are loose, corroded, or faulty
    use the DMM for to see if they in short Diagnosis
    Remember any circuit in CAN, use differente Baud rate, for Washing, Dryer, etc
    maybe you need to make Setting UP.
