Yes. That is what I'm suggesting.Ok - so you are suggesting to plug back to a 'dummy' connect to trick the onboard computer - is that right?
It's a newer model (used to us) so how might I figure out what to 'jump' to ? Electronics/elec not my strong suit
MB doesn't design/make the unit you unplugged, they install them. I would get the brand and model number so you you can search for the installation/wiring details. The information must be available for the installers. Armed with that someone should be able to help construct a dummy plug.
There is no defeat feature built in to the step unit? I would think that the designers would accommodate that. They must anticipate that the user doesn't always want the step moving out into the way. Check with the manufacturer.
Added: I haven't reviewed this "disarm" thread. The info may already be here.
