Possibly the parameter for the door open pick up (backlash speed?) is just too low and not enough poop to move the doors? Do they stall at near fully open? Hold them back at or near DOL and see if they'll pull through. Overall how do the door speeds look? Maybe torque is too low? Like Fred said, Doors open, the PI flashing and the car off line is definitely in the category of doors failing to close in the allotted time. Door ramps'l do it too, bad brushes'l do it. Broken collar on DOL/DCL limit? What is the Door Fault #?
Be sure to let us know what you found when you get it!
