    Car is a 2022 XLE AWD-E, specimen sitting for 2-4 months in dealer lot, no codes or issues - in ready to sale state of condition - 42000 miles.

    Powered on car normally and saw CEL, scanned and found history code C14DF (brake pressure control solenoid supply voltage circuit high)

    On Autel scanner, entering the ABS module (BRK) and erasing the code does not work. Performed reset memory --> codes for no linear actuator relearn --> performed relearn --> same condition

    Brake behavior is normal, fluid level is right below max and pads are in solid shape.

    My service info states that C14DF sets when "power source voltage for the linear solenoid is 16V or more for longer than 0.8 seconds".

    Sounds like you need a voltmeter and wiring diagram to confirm or deny if what the ecu sees is true or not.

    Will the code reset if the car is not "ready" (ie, only operating from the 12V battery - no DC-DC converter)?
