It is separate from the control unit in the cab. Usually it is located in the top of the basement compartment with the hydraulic pump. It controls what happens and is programmable. When you activate auto level, the system waits until there is 10 seconds in no change of the two level sensors. It then grounds the jacks one at a time. Comparing the stored level setting with the sensed level settings level, the worse out off level is corrected first. If the difference in the out of level exceeds the jacks capacity the system will not auto level. After the first level correction, the system proceeds to the other pairs of jacks until all jacks have pressures above 1,500 psi or the coach is level. If it is not level the the controller considers if there remaining out of level condition can be correct by raising a pair of jacks; if so, it raises the jacks slightly. This may happen several times. This is when the many consider this a thrilling ride. The problem is there is only circuit to move the jacks up and that is the retract circuit which has about 4 times the flow of the pressure circuit. This is so you don't have pressure in the fluid return system when retracting the jacks. If your system doesn't work that way, you may have a problem in the controller or logic module but first I would try reprogramming the level position in the computer.
Here's the zero point calibration.
Level Zero Point Calibration
Before auto leveling features are available, the Level Zero point must be set. This is the point to which the
system will return when an auto leveling cycle is initiated. To set the zero point (controller module must be
fully secured in production intent location), first run a manual leveling sequence to get the vehicle to the
desired level point. Then activate the Level Zero point configuration mode.
This mode is enabled by performing the following sequence:
1. Turn panel off. Then turn panel on.
2. Perform the following:
A. Press the Front switch 5 times.
B. Press the Rear switch 5 times.
3. At this point all LED outputs will blink, and the buzzer will be off.
4. You are now in IDLE mode ready to set Zero Point.
5. With a carpenterís level, manually level the coach. This will give the leveling controls the reference
point for the Zero Point Configuration.
6. When coach is completely leveled, manually press the Retract All switch 3 times to set the zero point.
For Diesel Units with Airbag Suspensions ONLY:
Note: You may also enter zero mode per above at anytime the system is in IDLE mode. The user then has
control to extend any pair of jacks while in zero mode in order to position the vehicle properly prior
