having trouble figuring out what the problem is with my Air suspension.
In an effort to fix my issue. right now the rear rises but the front is fully down. I changed the Valve block with no improvement. But when I disconnected the rear hose from the valve block, the rear came down. Is that a sure sign the rear valves are working??
And conversely if the front valves were bad, would it not air up??
I keep getting the error P1400 "below lower limit Exceeded, Control position not adjustable"
The pump stops running when that error comes up, if I clear it it will start again (but front doesn't move at alll)
the height sensor readings seem to be in the ball park.
