I have read that when you have an ALS, it automatically dumps the air first then commences the leveling process.
I have noticed that my front air suspension does not deflate as the rear ones.
1. Is there a recommended fix that I can accomplish myself to fix this?
2. Should my ALS activate my DAS Switch?
Onja, I have the same system (HWH with no jacks) and there are two ways to level. If you have jacks (or another system other than HWH) that extend to level, then disregard the info below.
First Way: Dump the air and then push the air level button twice. This method will level the coach automatically by raising the lowest point front to back and side to side.
Second Way: Do not dump the air. Push the air level button twice. This method will cause the system to lower the highest point front to back and side to side.
Both methods will get you level unless you are on a very steep slope. In this case, your pad will light up showing slope to steep. If you can't move, you may have to add a board or two under your low point wheels and try again.
The second method may leave you very close to your ride height if you are already close to level.
The first method will put you closer to the ground and make it easier to step out of the coach.
Just make sure that before you use method 1 or 2, that you put your slides out while at ride height and when you are ready to leave, you start up your coach bring the air up to achieve ride height before you bring your slides in.
Also, if you choose to dump the air first before leveling, make sure your steer wheels are straight and never move the coach until you are back at ride height.
ON EDIT: just saw you coach year and model at the end of your post. You can probably disregard what I posted above but it may help understand how the HWH system works.
