Ground"
No Response. • UGM Detects that the Leveling Jack Extend Valve (J2-32) is
reading a Short to Ground Circuit.
• Check valve connector for damage or faulty wiring.

Prevented. • UGM Detects that the Leveling Jack Retract Valve (J2-15) is
reading a Short to Ground Circuit.
• Check valve connector for damage or faulty wiring.
3533 3 5 “Leveling Jack Retract Valve Short to Bat-
tery”
No Response. • UGM Detects that the Leveling Jack Retract Valve (J2-15) is
reading a Short to Battery Circuit.
• Check valve connector for damage or faulty wiring.

4219 4 2 "Rear Left Module Temperature - Out Of
Range"
Drive Speed Restricted to Elevated
Speed. • UGM is detecting that the Left Power Module's Internal Tem-
perature Sensor is out of range. The Controller will need
replaced.
4220 4 2 “Rear Right Module Temperature - Out Of
Range”
Drive Speed Restricted to Elevated
Speed. • UGM is detecting that the Right Power Module's Internal
Temperature Sensor is out of range. The Controller will need
replaced.
4223 4 2 “Rear Left Module Too Hot - Please Wait” Drive Speed Restricted to Elevated
Speed if the Temperature is less than
105C degrees. If the Motor reaches
105C then Drive Functionality is Pre-
vented. • UGM is detecting that the Left Power Controller Temperature
is greater than 85C.
• Check the Controller's external temperature. If the controller
is hot, then allow the controller to cool. If the controller is
not hot, then the Controller may need replaced.
4224 4 2 “Rear Right Module Too Hot - Please
Wait“
Drive Speed Restricted to Elevated
Speed if the Temperature is less than
105C degrees. If the Motor reaches
105C then Drive Functionality is Pre-
vented. • UGM is detecting that the Right Power Controller Tempera-
ture is greater than 85C.
• Check the Controller's external temperature. If the controller
is hot, then allow the controller to cool. If the controller is
not hot, then the Controller may need replaced.
4228 4 2 “Rear Left Motor Temperature - Out Of
Range”
Drive Speed Restricted to Elevated
Speed. • UGM is detecting that the Left Power Module is communi-
cating the Output of the Motor Temperature Sensor is out of
range.
• Check the wiring between the Left Controller (CO371-J1 pin
22) and the Left Drive Motor (X425A pin 5) for an open or
short circuit. If the wiring is okay, then the Controller may
need replaced.
4229 4 2 "Rear Right Motor Temperature - Out Of
Range”
Drive Speed Restricted to Elevated
Speed. • UGM is detecting that the Right Power Module is communi-
cating the Output of the Motor Temperature Sensor is out of
range.
• Check the wiring between the Right Controller (CO342-J1
pin 22) and the Right Drive Motor (X424A pin 5) for an open
or short circuit. If the wiring is okay, then the Controller may
need replaced.
