Two stop Otis 211 with no leaks but will shut down after sitting idle for 5 mins with a valve fault on the on board diagnostic tool. When I sit on car top the tape readers door Zone LEDs stay lit and the Lu and ld lights never light up. But the car will eventually relevel up 3 or 4 times for no reason then level back down to floor level and shut down. I didn't have a meter one cause my helper lost it. Has anyone seen this before. Which is more probable the tape reader board or the io board behind CPU?
