Kneeling bus

[Jim Blackwood]

Thanks BW, it does have rear raise but operating that switch doesn't settle the rear down onto the bump stops. I want to drop it all the way down. Do you think there would be a way to do that with the rear raise/lower components?

In front the Kneel switch does that by energizing the Purge solenoid valve and venting the pressure from the airbags. Looks like there is a reference pressure involved in that too and I've forgotten exactly what that does, but I think it sets the minimum pressure in the bags at kneel. I'm looking for a way to do something similar at the rear.

It looks to me like the raise/lower might operate by changing a reference pressure for the system but I'm still learning how that works. I wonder if dropping that reference pressure to near zero would cause it to settle down onto the stops. I dunno, maybe the leveling valves would prevent that.
