Hi Bob,

I have 512, so I may be able to help with some basic diagnostics.

First, will the coach maintain travel height with the engine running? Do you know how to check that? What air pressure is on all three gauges with the engine running, and the coach in travel mode?

Second, the easiest way to reset the "brain" on our era is to remove the four screws that hold the HWH panel to the console, gently remove the control panel, and then disconnect it from the ribbon cable for a few minutes. We do not have the button that Larry is referencing. I spent an hour looking for it to no avail.

Call me 817 223 2056 if you want. Not busy today at all

Bob, one more thing. This thread became confusing to following when you mentioned the level sensing unit between the front tires.

The height control valve for the front is between the front tires, deep up into the suspension well. It controls front height when in travel mode.

The level control sensor that tells the HWH how to level the coach in level mode is well protected in a bay. I can take a picture of it if you are interested in what it looks like.
