Auxiliary Function -
A 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 “A” 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
33199
Auxiliary Function -
B Valve - Open Circuit
• The desired current is greater than 250mA, but the
actual current is less then 75mA
• The auxiliary hydraulic “B” digital output was open-
circuit. 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

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

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
