Seems 5th wheel ABS assembly giving lot of field failure issues specially in cold climate. Relay valve is not doing its work properly seems it is overloading with its function!
Release your tractor brakes and wait for the compressor to stop pumping air. Shut off your truck and don't set your brakes, you'll hear and air leak right away
Spring brake chambers or a QRC1 anti compound quick release valve may back feed through the service relay valve exhaust port .
