Is the lift stuck on top of car inspection? Have you tried running it from car top (with & without door lock bypass) I cant remember if the DOL is active high or low on those, is the car door closed or open?
I would check the top of car inspect wiring on the switch and the DOL sensor if it is in the wrong state.
Have you done the following resets? (M151, M152, M152, M2231)
