TROUBLESHOOTING
Corrective Action
Check the LEDs on the node to
ensure proper communication.
Identify and correct system errors.
Test the voltage (12V) and ground
at the disengage switch and
pressure transducers.
Adjust the disengage settings and/
or pressure switch knob.
• Replace the pressure switch.
• Replace the flow disengage
switch.
• Replace the transducer.
Test the voltage (12V) and ground
on the foot/enable switch cable
connection, using a jumper wire to
simulate foot/enable switch
function.
Adjust the Disengage Setting in
the field computer.
Turn the knob on the pressure
switch out.
Replace the faulty pressure
disengage switch.
Replace the faulty flow disengage
switch.
Reverse the left and right steering
hoses on the machine's steering
