Fork Tilt Down Valve -
Open Circuit
• The desired current is greater than 250mA, but the
actual current is less then 75mA
• The fork tilt down digital output was open-circuit.
This fault may be caused by improper wiring or a
control module issue.
Yes
33195
Fork Tilt Down 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 fork tilt down digital output was shorted to
ground. This fault may be caused by improper
wiring or a control module issue.
Yes
33196
Auxiliary Function -
A Valve - Open Circuit
• The desired current is greater than 250mA, but the
actual current is less then 75mA
• The auxiliary hydraulic “A” or “B” digital output was
open-circuit. This fault may be caused by improper
wiring or a control module issue.
Yes
33197
Auxiliary Function -
A/B Valve - Short To Battery
• Fork Tilt Up & Down, Auxiliary Hydraulics
functionality prevented
• The auxiliary hydraulic “A” digital output was
shorted to battery. Auxiliary hydraulics will be
prevented until the next power cycle. This fault may
be caused by improper wiring or a control module
issue.
• Active when Machine Setup’s AUX HYDRAULIC is
set to ENABLED
• The desired current is 0mA and the digital output
driver’s diagnostic feedback is low
• Low-Side Fault Relay de-energized
Yes
