Automatic steps can be very confusing. On our old '85 Class C, to add to the confusion, they were vacuum powered. Two 18' rubber hoses ran all the way from the inlet manifold to a pair of vacuum actuators at the steps.
Current rig has electric, but they're confusing sometimes also. As you come in the door, there's a switch panel at carpet level alonside the inner steps. One of those switches will hold the steps in whatever position they were in when you switched it (ignition OFF). When you turn the ignition ON, they retract irrespective of that switch. If you switch ignition OFF again, they don't come down until you operate the switch by the door. Once down, you have to operate itagain to keep them down. They also retract sometimes for no reason I've figured in 12 months using them.
I think either Rube Goldberg or his British counterpart, Heath Robinson, had a hand in the design.
