What are some common problems with the auto leveling air bags, I am having issues with mine not working, leaving me with extremely bumpy rides,and raising but not raising and lowering when they need to be up with a trailer connected!
I just redid my system, for me the rear bag was leaking, I bought new bags, installed, evacuated the air tanks and refilled to 175 psi nitrogen, used scan tool to short fill and then complete fill, all functions came back..
To answer your question, low air pressure. I bet is your main issue, and it’s probably caused by a leak.
