Obd adapter

  • My experience with BWA Engine and Bosch MED 9 ECU:

    • OBD communication needs adapter because KTM changed CAN High and CAN Low Signal Pin (or you simply change the pins)
    • VCDS manufacturer communication --> works
    • VCDS EOBD/OBD II communication --> does not work (see screenshot from VCDS)
    • EOBD/OBD II communication via HHOBD Device --> does not work


    Is VCDS Manufacturer communication based ond KWP2000 Protcol?

    Which tool is necessary to unlock EOBD on MED9 BWA engine ECU?
