    I connected VDASH to my 2019 Volvo XC40 and ran the VDDM "Initialization Check" function. The procedure completed successfully and reported "OK".

    Immediately afterwards, the parking brake behavior changed:

    The electronic parking brake can still be applied normally using the center console switch.
    The parking brake will NOT release using the center console switch.
    The parking brake CAN be released through VDASH ("Release parking brake" function).
    The vehicle drives normally once the brake is released through VDASH.
    No brake warnings are displayed on the dashboard.
    No ABS or BCM fault codes are present.

    The only relevant fault code that appeared is:

    VDDM-B111153
    "Electric park brake enable. System Programming Failures. Deactivated."

    Service mode was never activated. "Exit service mode" returns an error because service mode is not active. The issue started immediately after running the Initialization Check.

    Has anyone encountered this before or knows how to restore normal parking brake release operation after a VDDM initialization check?

    @T5-T6-Schnappi Not Rica, it was NRS TEchniek but i think the procedure it's exactly the same.
    I don't have DoIP communication in Vdash and Orbit (It was only the 2 softwares i tried)

    I've done some meetings with NRS and Orbit support. During this meetings they've tried to connect the car to the software (Orbit) with no succcess because there's no ethernet signal/connection from OBD port. Mostly, their work was done around the windows firewall and windows Ethernet/port configurations. Basically, in the end this was their answer:

    " Although not see a 2022 VCM fail, this is what we see on early VCMs that have failed, at least for our purposes. The Ethernet chip fails, wich kills the VOE connection."

    Just to let you know, during this time i've checked the OBD Port pins, the fuse for OBD diagnostics, also perform a de-power for reset the VCM module (Disconnected the VCM module and VOC battery backup). Thanks

    Ach stark ☺️

    Danke dir schonmal für die hilfreichen Tipps.
    Wenn ich aus dem Urlaub zurück bin, werde ich direkt das CEM checken und die Steckverbindung an der A-Säule höher der Klappe des Handschuhfachs hinter der weißen Abdeckung.

    Werde mich danach nochmal bei dir Rückmelden.

    @Kurt1977 I think I'm getting old. 🤔

    The official guide recommends cloning the software and than perform SRS configure. As your original module has a checksum error indicating corrupted software or a bad EEprom , cloning won't work.
    You can try to just perform the SRS configure if you install a used module hoping the software is the same than in your original module or at least compatible with your car. If this doesn't work you will need an official VIDA subscription to perform a software reload, but this will only work if the software for the donor part is still present on the servers and if VIDA thinks the part number is somehow compatible with your car. Volvo has started to remove lots of softwares and part numbers for superseded/discontinued modules from their VIDA servers making software downloads impossible for those parts.

    You can also try to contact some specialists for ecu repairs and ask them if they can fix your original module.
