We're on-site right now but cannot get the cab to move at all. IMS shows it to be stuck in what I call red door mode. On the I/O screen, DLB, DLT, NTSB, and NTST are all green. The technician has attempted numerous things. I've also registered him an account on this forum so he can better explain things himself, however I'm hoping the admin approval time isn't too long.

Anyone have any ideas on what we might be able to do to get this cab going so it can perform a hoistway scan?
