2000 XL2 NO AUX AIR PRESSURE
Have been fighting a hit and miss suspension issue for a couple of weeks. The coach builds air but the Aux guage reads zero on the dash. Air at the aux bus side is equal to the primary and secondary tanks. Manually manipulating the valves from the HWH results in clicking but no air movement as too the switch on the drivers ledge near the parking brake release.
Air in the bags is zero. Any idea of what line feeds the aux tank? does it originate from the air dryer?

Do you have air for the parking brake?

The question should read “Do you have air to RELEASE the parking brake.” Little or no air in the system would SET the parking brake. You would not be able to move the coach.

Just to confirm what you’re saying, air pressure in the brake system (primary/secondary) comes up normally but the suspension never airs up (i.e. comes up to travel height)? Is that correct?
