9-65 G6-42A, G9-43A, G10-43A
Electrical System
33200 Auxiliary Function -
B Valve - Short To Ground
• The actual current is greater than 200mA, PWM is
95%, and the digital output driver’s diagnostic
feedback is low
• The auxiliary hydraulic “B” digital output was
shorted to ground. This fault may be caused by
improper wiring or a control module issue.
• Active when Machine Setup’s AUX HYDRAULIC is
set to ENABLED
Yes
441 Battery Voltage Too Low -
System Shutdown
• Fork Tilt Up & Down, Auxiliary Hydraulics & De-
Clutch functionality prevented
• Battery voltage is less than 8.0V so the control
module has prevented associated functionality.
No
442 Battery Voltage Too High -
System Shutdown
• Fork Tilt Up & Down, Auxiliary Hydraulics & De-
Clutch functionality prevented
• Battery voltage is greater than 8.0V so the control
module has prevented associated functionality.
• Low-Side Fault Relay de-energized
Yes
447 Reference Voltage Out Of
Range
• Fork Tilt Up & Down, Auxiliary Hydraulics & De-
Clutch functionality prevented
• The control module’s +5V reference was
measured greater than 5.4V or less than 4.6V for
1000mS. Since this reference voltage supplies the
joystick(s), fork tilt and auxiliary hydraulic functions
must be prevented.
• Low-Side Fault Relay de-energized
Yes
998 Eeprom Failure -
Check All Settings
• Fork Tilt Up & Down, Auxiliary Hydraulics & De-
Clutch functionality prevented
• The control module detected an issue with the
non-volatile memory used to retain Personalities
and Calibrations. Verify all settings using the JLG
Analyzer.
• Low-Side Fault Relay de-energized
Yes
2239 Function Problem -
Joystick Calibration Faulty
• Fork Tilt Up & Down, prevented
• The joystick calibration has never been performed,
is improper or calibration attempt has failed. Re-
calibrate the Fork Tilt and Auxiliary Hydraulic
(optional) joysticks to clear this fault.
• Auxiliary Hydraulics prevented if Machine Setup’s
AUX HYDRAULIC is ENABLED
No
