Ride height valve failures

HOWEVER, I now have a red lite(DS Rear) AFTER moving about a block down the road. When I level the coach from a full air dump, all red liters on all corners are on....good! Then sw to travel mode (HWH500) lites are off, good. move about a block and the DS corner red lite comes on. The red lie will flicker over a harsh bump. When leveled for an overnight, there is no loss of air...pump does not come on.
Have tried to call HWH and after three days they CB and my phone does not connect...twice.
The FL tech set the ride height on the frt and PS. Maybe the DS needs to be set?
I measured the fender wells for reference. Side to side shows DS about 1in lower than PS. Hmmmm. Any ideas?

I would be suspect of the driver side rear "Travel Solenoid". That solenoid opens the air path for the ride height valve when in Travel Mode. If the travel solenoid is INOP you will have insufficient air in the air bag and will see the intermittent red light when in travel mode.


My CC is an older 1997 but still uses the HWH 500 series system. The red light when in travel mode on my coach comes from the pressure sensor for that specific air bag. If the pressure is low, you get the light on the dash when in travel mode.

So, this Wed the coach will have the ride height checked on DS rear, travel solenoid inspected and the air dryer kit replaced.
I'll get back on here after I find out more.
Thx, Bob

Had the coach in at Source Engineering for another issue and asked them to diagnose and fix the DS rear red light. They did fix the problem with adjusting the ride height of the DS rear and the PS rear and the Front. So far so good for my travels. I do believe Source Engineering has this Karma thing for difficult and challenging chassis issues.
This experience reminds me of a FOOSBALL challenge.

Dump the air and then let it come up to travel mode ride height. Take a tape measure and measure left and right sides at the center (I use my wheel center cap as a quide) of the wheel arch. That will tell you whether you have fixed it or not.
