Possible Cause
Hydraulic connections are plugged
or not properly connected.
No high current power
Cable is improperly or not
connected.
There is a short or break in the
cable.
The PWM Max settings are
incorrect.
Flow control valve is closed.
(SmarTrax hydraulic valve part
numbers 334-0003-056 through
334-0003-079 only)
The left and right proportional
solenoid connections are reversed.
The left and right hydraulic
connections to the SmarTrax valve
are reversed.
There is an internal leak in the
machine's steering orbital.
A SmarTrax valve cartridge is
leaking.
The machine may have a reactive
steering unit.
There is a failure in the dual
counter-check valve (if applicable
to the SmarTrax kit installed).
SmarTrax is not engaged.
The GPS signal is hindered by the
GL1DE speed filter.
The LA Aggressiveness setting is
too low.
The OL Sensitivity setting is too
low.
Corrective Action
Check the hose connections.
• Check the node status lights for
high current (HC) power.
• Check the power/ground fuses
and connections.
Check the solenoids on the
SmarTrax valve for proper
connection and voltage.
Inspect the cable for shorts or
breaks.
Verify PWM Max settings are set
correctly in the field computer.
Verify FC adjustment is turned all
the way out. Typically eight or nine
threads are visible beyond the jam
nuts.
Verify all solenoid connections are
connected to the correct coils.
Reverse if necessary.
Verify all hydraulic connections are
connected to the correct ports.
Reverse if necessary, if applicable.
Check for and fix leaks in the
steering orbital.
• Swap the left and right
proportional cartridge (if
applicable).
• Replace the SmarTrax valve.
• Verify the steering unit type
functions properly.
• Verify the blocking valve is
installed correctly.
Replace the dual counter-balance
valve or dual check valve.
Engage the SmarTrax system.
Disable the GL1DE speed filter.
(Phoenix 300 receivers only)
Increase the LA Aggressiveness
setting.
Increase the OL Sensitivity setting
in increments of 1, allowing at least
40 seconds between adjustments.
