Found this: http://forum.bacrallies.com/m-1345317727/ It may help a little, but it does not say exactly where the reset is. It does say there is a reset though.
I also found this: http://www.hwhcorp.com/ml32304.pdf This file speaks of a "lighted reset switch" and a "master warning light." I am thinking you and I have near the same coaches, at least the same HWH leveling systems. I don't remember seeing a "lighted reset switch," nor a "master warning light." This file doesn't tell us where these two things are, except that in the picture it shows them below the key panel. My coach is at the shop getting fluids changed until later today. I will take a look later when I get the coach back from the shop.
