ALWAYS VISUALLY CHECK TO ENSURE
JACKS ARE FULLY RETRACTED BEFORE DRIVING OR
Your jack system is microprocessor operated with features built-in to handle many different
leveling problems. The system consists of the jacks with mounting brackets, a control console,
wiring harness, motor pump, level module, dash mounted controls (on some models), bong (warning) alarm, and a valve complex with manual retract provisions.
1. Motor home should be in parking gear during operation of the leveling system. Ignition key
should be in ignition position, although some coaches were configured from the factory to
operate with the key in the accessory position.
2. Turn on the switch labeled "POWER" on the control console. One of the red lights located on
or under the dash will also go on when the "POWER" switch is activated. All lights on the
control console should flash on for at least ¼ of a second (except the "WARNING JACKS
The initial powering on of the control console performs a self-diagnostics test. If either of the
green lights is on, the system will remain inoperative, indicating a short in the system or a
malfunctioning control console.
If powering on produces no lights, check for burnt fuses. A fuse for the control console is
located at the lower end of the box at the bottom. To gain access to this fuse, remove the one
inch perforated plastic cap. The fuse is located on the printed circuit board inside this opening.
Remove the fuse with a small screwdriver and replace with an AGA 15 fuse, NO LARGER.
Another fuse or circuit breaker is also located under the dash. See wiring diagram.
Once the system is powered on, one or two yellow lights may be illuminated. Whichever yellow
light or lights are on, indicate that particular jack or jacks need to be lowered in order to obtain a
level condition. If no yellow lights are on after initial power up, your coach is level.
