    BCM PQ25 LongCoding "CAN-Powertrain Loop active"

    Hallo, what does this setting "CAN-Powertrain Loop active" in Bit 5 of Byte 25 of the BCM PQ25 mean ?




    I am aware that the Gateway is included in the BCM, so i assume this setting hase something todo with the Gateway ?

    But what exactly will it do ?

    Greats

    So i managed to find the Explanation in the German VCDS DRV Version
    It looks like Byte 24 Bit 5 is wrong Documented in the English VCDS Version.
    The German Version has a better Text Coding for this bit.



    This is probably good Translated to "Engine CAN keeps still running for some Time after Klemme 15 was shut off"
    And anyhow the German Version has way more Informations regarding PQ25 BCM Coding than the English one.

    Anyhow, can someone fix this in newer Versions of English Version please ?
    And when you already working in it you can Add a new Text for Byte 29 Bit 6 in German and English version.



    Since it looks like this Bit is Documented nowere till now.

    Byte 29 Bit 6 Set ==> MFSW is connected to BCM via LIN Bus Pin 36 on T73b (normal Use Case on EU6 Diesel Engine)
    Byte 29 Bit 6 Not Set ==> MFSW is connected to BCM via LIN Bus Pin 17 on T73b (normal use Case on EU5 Diesel Engine)

    Thanks and Greats
