725 TROUBLE SHOOTING GUIDE
On the right hand side of the touch panel there are four (4) red and four (4) yellow indicator lights. The four red indicator lights
are JACK DOWN warning lights. There is one light for each jack. These warning lights come on when their respective jacks
are extended about 1/2 to 1 inch. The four yellow indicator lights are level indicators, front, left side, right side and rear. A lit
yellow level light indicates that a side, end or corner is low. When all four yellow level lights are out, the vehicle is level within
the tolerance of the level sensing unit.
Use the UP ARROW (Extend jack pairs) and DOWN ARROW (Retract jack pairs) buttons to extend jack pairs as needed to
level and stabilize the vehicle. Side level lights should be turned off before turning off front or rear level lights. Stabilizing should
The ignition must be in the "ON" or "ACC." position and the park brake must be set to use the system. The "NOT IN PARK/
BRAKE" indicator light will come on while pushing an UP or DOWN arrow manual button if the park brake signal is not present.
MANUAL OPERATION
If applicable, use the DUMP button to dump the air before extending jacks. Air should be completely exhausted from the vehicle

suspension before starting a leveling process.
Excess slope is when two jacks extend as far as they can without turning a yellow level light out. The pump
will go to relief and trip a 3000# pressure switch on the leveling manifold. The "EXCESS SLOPE" light will come on. Jacks
that have not been extended will not extend when the "EXCESS SLOPE" light is on. The "EXCESS SLOPE" light will be on
whenever the ignition is on until the park brake is released (with the ignition on) or the jacks are completely retracted with the
The "CANCEL" button will stop the automatic leveling process any time. After pushing the "AUTO LEVEL" button to start the
automatic leveling process, pushing the "AUTO LEVEL" button again or pushing the "STORE" button will stop the automatic
leveling process. If the vehicle is equipped with remote leveling system rocker switches, pushing the rocker switch to "LEVEL"
or "STORE" will stop the automatic leveling process.

STABILIZING: Each jack has a pressure switch. When the jack pressure switch is on, the computer knows that jack is on the
ground. Because of possible thermal contraction, it is important that all jacks have lifted the vehicle at least 3/4 of an inch. This
switch can be adjusted. The stabilizing mode has a specific sequence. The computer first checks the right rear jack pressure
switch. If the right rear pressure switch is off, the computer extends the right rear jack until that pressure switch comes on. If
the switch is on, or once the switch comes on, the computer then checks the left rear jack pressure switch. If the switch is off,
the computer extends the left rear jack until its pressure switch comes on. If the pressure switch was on, or once the switch
comes on, the computer rechecks the right rear jack, extending it if necessary. The computer then rechecks the left rear jack,
extending it if necessary. After checking and rechecking the right rear then left rear jacks, the computer then checks both front
jack pressure switches. If either pressure switch is off, the computer will run the pump and open both front jack solenoid valves.
When the computer sees both front jack pressure switches the computer shuts the pump off and turns the solenoid valves off.
If all yellow level lights are off, the system is now done.
LEVELING RECHECK: Because the coach can be "bumped" slightly during the stabilize procedure, a yellow level light can
come on during stabilize. If a yellow light comes on during stabilize, when the stabilize procedure is finished, the computer will
extend jack pairs as necessary to turn any lit yellow level lights off. After turning the level lights off, the computer will turn off no
matter what position the jack pressure switches are in.
