i worked on this car a few months ago, had a problem with floor count, ended up having to relearn the hoistway. car has ran fine since, then the mechanic tried to access car and this problem arose. i believe i left the car inspection speed at 35 or 50 whatever it said in the paperwork for hoistway learn. had a hard time getting it to learn. had to eventually remove the battery and also short out the pins where battery plugs in,on the mcss board in order to finally get a learn run. its been a while, so maybe i inadvertently changed something i should not have while trying to get car to learn. although the car runs fine on cartop inspect.
