hey jim, it depends on the software version, usually if the car relevels 6 or more times without making a normal run, the car will fault out on a relevel fault. you can test this by making the car relevel without a run, count the relevels and see how many it takes to shut the car down. if you dont have a tool, look at the hrv led on the relay board, if it goes out, the car has faulted.
