Failure to follow the steps in this guide can cause irreparable damage
to the electronic components in the steering system!
7.9 Error Code 111 - Right Actuator Fault
7.9.1 Perform a visual inspection of the right actuator wire connections and
associated wiring. Inspect the mechanical parts to make sure no
hardware is loose and the jam nut is tight. If no faults are found
proceed to next step.
7.9.2 Turn ignition switch ON. Watch for movement of the right actuator
when the right joystick is moved to full forward and full reverse
positions. If there is little or erratic movement, turn ignition switch OFF.
Inspect that the jam nut at the bottom of the actuator cylinder is tight.
If the nut is loose it will have erratic or no movement as the drive barrel
will spin on the threaded rod end. See section Removal and Installation
of Electric Steering Actuators to replace actuator. If the jam nut is tight,
proceed to next step.
7.9.3 Disconnect the wire connector labeled M1 at the actuator. Use a digital
volt/ohm meter, check actuator motor resistance at the motor wire
connector. The motor resistance should be 0.2-1.0 ohms. If the
reading is higher than 1.0 ohms, replace the right actuator motor. If
there was no actuator movement, the jam nut was tight, and the motor
resistance is correct, proceed to next step.
7.9.4 Be certain the ignition switch is turned OFF. Connect the black lead of
the digital volt/ohm meter to the battery ground on the right rear frame
of the machine. Set the meter to the DC voltage scale and check
terminals of the wiring harness side of the M1 connector. The orange
and the black wires should read battery voltage with the ignition switch
OFF. Turn ignition switch ON and check the wires again. With the right
joystick in the centered position, the meter should read 0 volts.
Connect to the orange wire and move the right joystick to the full
forward, back to center and to full reverse positions. The meter should
read battery voltage in one direction but read 0 VDC in the center and
opposite positions. Perform the same test on the black wire, readings
should be reversed. Proceed to next step.
7.9.5 Be certain the ignition switch is turned OFF. Disconnect the motor
connector from the M3 actuator motor. Cut the wire ties so the wiring
harness side of the M3 connector can be connected to the M1 actuator
motor.
Do not connect the M1 wiring harness to the M3 motor at this time!
Doing so can cause irreparable damage to the electronic components
in the steering system!
