I have a valid level system the rear wil not air up at all and shows a fault not allowing the rear 6 pack to go into travel mode.. to get me where I need to go does anyoneme know if you can bypass the 6 pack all together ? Just hook supply straight to the bags so I can get about 20 miles down the road?
Hooking the bags straight up to the air will add more air than they should have, leaving the drive axle light. You can make it work two different way: 1) tee the lines to the air bags together, add shutoff valve between the tee and the air supply and then manually sneak up on the needed pressure, 2) electrically disconnect the 6-pack and then manually energize the "raise" solenoids until you reach the desired pressure., leave the 6-pack isolated (probably ought to do this in both cases so that the controls don't do something funky while under way). These two approaches only work if the air bags reliably hold pressure. If not, then you either have to stop and re-air the system or you are stuck until you solve the leaks.
does the valid leveling system have 6 packs like the hwh one?

As I understand the leveling system
Air is supplied to 6 pack
The 6 pack supplies air to the leveling valve
The leveling valve (HCV) sets ride height
If I’m correct air supplyed to the HCV should raise coach
If I’m wrong, someone please correct me

George,
With plenty of air pressure supplied to the 6-pack, the travel coils must be energize for the coach to react to the HCV. A blown travel fuse in the HWH box will prohibit the coach from going to ride height.
His coach doesn't have hwh. It is valid

IF you by passed a non working 6 pack AND sent air to leveling valve
The coach should raise??
Hot wire the two travel solenoids in the rear.
Richard, do you mean disconnect each rear travel solenoid At the plug, and make a jumper to a 12v source? Attached is a picture of Gordon’s troubleshooting device that seems to be perfect for this situation, just unplug the solenoid and plug in this jumper
Geogeb, I agree with straight to HCV. But if using air from 6-pack, travel valves must open. Just fixed a coach with shorted wire that blew travel fuse resulting in no travel function. Raise and lower worked fine.
