    MK4 electric window, central locking, canbus communication.

    Golf MK4 1,9 TDI, 2003

    I get the following error codes:

    5 error codes found:
    01336 - Corporate database bus comfort
    37-10 - Defective - Periodic
    01336 - Corporate database bus comfort
    49-10 - No Communication - Periodic
    01330 - Central control unit for comfort system (J393)
    49-10 - No Communication - Periodic
    01331 - Driver side door control unit (J386)
    49-00 - No communication
    01332 - Passenger side door control unit (J387)
    49-10 - No Communication - Periodic

    I have tried:

    Check both door harness for broken wires. Bran new harness in driver door side.

    Tried another motor/controll module in left side door.

    Disconnected all modules, measure both CAN wires to all modules to ccm module and instrument cluster.
    No broken wires and no short to ground or positive.

    I can measure 1,5 and 3,5 volt in the CAN wires in the door module.

    Tried another instrument cluster which is configured for my vehicle.



    Do any of you guys know what I can try next ?

    Hi and welecome.

    Please post a complete Auto-Scan using the English version of VCDS. You can download it from this page an it will happily co-exist with the translated (Danish?) version that you are currently using.

    Hi. Yes I am using the Danish version. That is also why I did not uploaded the complete scan.
    I will try download the English version and make a new scan.
