    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.

    I would suspect a defect wheel speed sensor, corroded sensor ring at one of the wheel bearings, or low battery voltage.
    Put the car on a lift and check the signals of all sensors with an oscilloscope. The sensors could still be working, but the sensor rings could miss one or more teeth which results in sending nonsense signals to the BCM.

    @Cookie_69 wrong forum for such questions. Vdash won't be useful for any of your questions.
    Engines with Bosch throttle body require a different ECM. Those ECMs are not compatible with your CEM, so you need another CEM and somehow adopt it to your car. And so on.... Absolutely not worth it. You will basically need to update your whole car to the electronics of a 2005+ Model.
    Get the correct engine for your car, or scrap it and get a new car.
