Shuts down at the top floor (2stop). Reset and will run fine until I leave then it shuts down again. The Xtra info states that it is out of sequence when coming down, yet it's at the top floor when I get here. I have replaced the KLU sensor and the CIO board. All sensors seem to be functioning properly as all the LEDs light up accordingly on CIO and CRIP board. Also the car will park at bottom and relevel itself every minute or so even though the sensors don't change states nor is the car is leaking down. Any thoughts or suggestions would be greatly appreciated.
