7.16 Error Code 231 - Left Load Pin Open Circuit
7.16.1 Check the left load pin L3 wire connections. Perform a visual
inspection of the left load pin L3 and associated wiring. If no faults are
found proceed to next step.
7.16.2 Use a digital volt/ohm meter to test for voltage at the black P2 control
board connector. Turn ignition switch ON. Connect the black meter
lead to a common ground. With the red meter lead, back probe the #7
terminal at the black P2 connector. The meter should read battery
voltage. If no voltage is present, replace the control board. If voltage is
present, back probe the #8 terminal at the black P2 connector. The
meter should read 2.5 +/- .2 VDC with the left joystick in the centered
position. If no voltage is present, replace the left load pin L3. If voltage
is present, move the meter ground lead to terminal #9 of the black P2
connector. Move the red meter lead to terminal #7 of the black P2
connector. The meter should read battery voltage. If no voltage is
present, keep the black meter lead inserted in terminal #9 and move
the red meter lead to the alternator battery terminal. The meter should
read battery voltage. If voltage is present, replace the left load pin L3.
If no voltage is present replace the control board.
7.16.3 After replacing the failed component make sure to reposition the wiring
harnesses in the correct configuration and secure with wire ties. Turn
ignition switch ON and test the functionality of all 3 circuits; right, left,
and side.
