Air tanks are holding air fine.....HWH panel is not lit and "level coach" is flashing.

If no lights on HWH control pad, possible connector has come loose on back of control pad.
If you have been down a bumpy road, possible that the linkage fell off your front ride height valve, which caused bags to dump air.
I checked the plug all is good...fuse ???? I'll get under and see ..
If the dash gauges read in range and the emergency brake stays off. IE air system intact , front ride valve must be out of range or the line into that end broke.
I had the ride valves get knocked out of adjustment quite often on parts of 401. Super rough roads even going slow.

Yes on linkage mine is kinda wimpy
I think Hans is on the road.
Thx all for the great responses. Called MOT support and Aubrey relayed some check points.
Mike (protech) exactly what happened...the entire "guts" of the front air leveling valve were missing. Lots of rough hwy up near Pittsburgh. Had a spare valve with me and changed it. 3hrs later ( had to pick up a brass 1/4 plug from HD) we are back on the road.
Chuck ...much appreciate the schematic...
Tim...Thx's for the MOT ref
Now to get a good nights sleep at a Hwy79 rest stop.
Thanks for all your help. We were in trouble yesterday. Hans worked soooo hard trying to fix the problem, and guess what....he fixed it. Just intime for Coach-net to stop by. Thankful also for the State police sitting behind our coach with flashing lights. We were in the middle of north and south construction lanes and a joining of Highway 70 and 79, south of Pittsburg in a little emergency turnout. I did take a video of Hans working on the air leveler and will try to post it here, if I can figure it out.
Glad you were able to diagnose and get back on road. Quite a story and quick turn around....
When our front ride height valve failed (but with the guts in place) we made a temporary fix that kept us able to drive for a couple of weeks ...
Remove front linkage to front ride height valve (center of front axle), then manually rotate valve to "fill" position, when bags are filled where we need to drive, rotate back to center off position, then tape around valve to keep it in that location. Repeat as necessary.
Ride height valve has three very close setting, empty, off, fill. Rotate slowly as each setting is very close to the other settings.
Barry that is information that needs bookmarked or put on Beaman arm info.
Larry, Your recommendation is completed:
