    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?

    @pvm I can't tell you if Vdash is capable to clone HCMs on SPAs. But you will see if this option is available in the clone menu. CEM pin shouldn't be required for this. Your ENET/DoIP adapter is perfect for software updates/cloning and recommended on SPAs. J2534 is only for older plattforms and also good for pin cracking on SPAs up to 2021.

    @330hpwagon I'm not sure if your car supports HDC. The official manuals mention HDC only from model years 2015.5 onward as this feature was officially introduced with the Cross Country models and is activated by default on these models only.
    To use HDC you have to manually shift to 1st gear or R. You can't activate it when in D or above 7 km/h.
    VIDA doesn't mention anything about specific hard- or software that has to be installed or that this function is only available from a specific structure week like other functions like ERS.
    The DTCs in your BCM are also all yellow which means they are temporary/historic/not active while the others in red are permanent. The first one in the CEM is from LED bulbs at the license plate and can be ignored. The others should be the ones that you want to adress.

    Why exactly do you even want to activate this function? I have a V60CC with this function and never felt the need to go downhill with less than 10 km/h.

    @Kurt1977 here is a little info about BCM replacement. The module must come out of a car that is similar to yours. Same model year, engine, transmission if possible. Part number can be different but must of course be compatible with your car.
