    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?

    @Libelix That will hurt your bank account. New VCMs are really expensive.

    You will need to revert all changes done with Vdash and OrBit. The CEM configuration has to be the one that is known to the VIDA/Volvo servers in sweden or the car will be blacklisted.
    If the independent has paid for a VIDA license which includes software reloads he should be able to do this. But the price for the software reload will be the same or even higher than by the official dealer as the license fees are very expensive, and almost every software package has to be bought like a "spare part". Ask for an offer first.

    @Atlantic28 create a support ticket here and ask if they can prepare a software reload for your DIM. Maybe there is no automatic fix for your software version yet.

    @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.

    Or maybe just disable it in the ECU?
