David,
Along with the suggestions that have been made you need to look for a little square box mounted to the back of the step housing. Not only does it have wires coming out of it, it has several air lines connected to it. This is known as your shuttle valve/ Norgen valve that transfers an electrical signal to an air movement. Check the wiring plug as it may have a loose wire there. If so and movement can cause a false signal causing the step to open and close at strange times.
