At both of the six packs you will find pressure sensors. At the rear six pack is a sensor that makes or breaks at about 60 psi IIRC. Those sensors go bad. Newell’s solution is to unplug them.

HWH put them there to keep the chassis from going flat on the air bags and possibly twisting too much.

If that sensor in the rear is kaput you will get the leveling light.

That light is there to tell you that you don’t have enough air pressure to drive away.
