For weeks now I have had an Otis gen2 mrl continually fault out on the bottom floor with doors shut and a 2907 ucm fault. Today upon arrival I also had a 2848 bds fault with it. Funny thing to is every once in a while when the 2907 takes place it also triggers fire service on that specific car (it’s a duplex). Today I had to reset fire svc as well.
So far I have checked/adjusted brake switch, cleaned brake switch, checked bottom floor interlock/contacts, checked the cps and cleaned, adjusted clutch to make sure rollers not actuating upon movement
Still, the issue persists. Any ideas?
