Gen 2 , 8 stop, gets stuck on random floors after resetting you will get 10 to 30 runs. Car cop buttons don't light, you can hit DOB, and exit, I have a tool I register no faults, on any boards, and car reads nor and correct floor position. All lights locks ect. Are made! I can run the car on ph2 all day. I think it's a security interface issue w/ the building, but not sure any suggestions?
