    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.

    @Phantom244 your error codes might be the result of water ingress from clogged sun roof drainages.
    You can check the grounds under the driver and passenger doors for corrosion.

    But there usually would be more codes if those are corroded as there are several modules connected to those grounds.
    On cars with sun roof it's a known problem that water gets into the fuse boxes behind the glove box when the drainage is clogged. Your error codes for a to high signal from the humidity sensor that is located behind the rear view mirror and a code for a bad antenna signal are also indicators that water might have reached places where it doesn't belong to.
    A loose windscreen that lets water in is also pretty common on P3 Volvos.
    Are there really just the three codes you posted, or do you have more DTCs? Also temporary ones would be interesting.

    @T5-T6-Schnappi Thanks for advice, i borrowed other cable and everything worked out. Also it works with different part/hardware numbers too( added picture). If it will be useful to anyone, it is enough to buy ETM by model year, the codes may differ.
