    Hello all.

    Accidentally let the brake caliper get pushed all the way out when replacing a wheel bearing.

    Brake alarm sound started.

    Unplugged the 12V so caliper would no longer get pushed out.

    Finished the repairs, replaced caliper, bled it using gravity method.

    No codes seem present, no error lights. Sound remains. I assume the power brakes are off still.

    No codes seem to blink with the "diagnostic" screen (paper clip screen LOL). Doing the "ABS reset" there seems to do nothing.

    Still have the car up on jack stands.

    Any advice? :)

    Do you mean all the dash lights are doing the steady half-second fast blink?

    If it powers up in ready mode and no codes and lights then jump the two pins with the paper clip routine and press brake pedal 8 times to clear the alarm sound, then take it for a test drive.
