Hmm i've never had them with manual accordian doors before, only centre opening auto doors. In this case the doors do an open and close check sequence before the car can operate otherwise it shuts down and only drives on inspection.
What i mean is just flick the car on inspection and back to normal and sometimes it clears certain flashing faults. If you can't access the car top or there is no ero operation from the controller, you can remove the wire and put it back in the terminal strip (2c4 or 2H4 something like that, check the print) and it will also reset it this way.
