Hey John, it's probably loose wiring between the door switch and the control module of your step and when hitting bumps its causing the connection to come and go which then makes the steps think the door is opening and closing. So while it's not fun you'll want to go over the wiring of the switch and see if you can figure out where the issue is and fix as needed. It could also be the switch itself has come loose so check that as well.

Hi Jameson I gone through checking the obvious, visibly checking connections( that are visible ), the magnet at the door opening. I can't check the wires from the magnet into the walls of the coach. I don't know how to do a diagnosis when this only happens intermitantly when the moho is being driven. I'm baffled. John

@John It could then be the control module. Maybe it has a shorted out board or something internal that's going bad. Do you know which model Kwikee step you have?
