7.13.3 Turn ignition switch OFF. Remove the black P2 connector from the
control board. Remove the orange locking plug from the front of the
connector. Use a small screwdriver to release the locking tab and
remove terminal #3 from the connector. Be sure to isolate the terminal
from any metal surface. Install the orange locking plug and reinstall the
connector. Turn ignition switch ON. Connect the red lead of the meter
to the black wire from terminal #3. If voltage is present, replace the
right load pin L1. If no voltage is present, insert the red meter lead in
terminal #3 of the black P2 connector. The meter should read 0 VDC.
If voltage is present, replace the control board. Be sure to reinstall
terminal #3 into the black P2 connector, Reverse procedure to install.
7.13.4 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.
7.14 Error Code 221 - Side Load Pin Open Circuit
7.14.1 Check the side load pin L2 wire connections. Perform a visual
inspection of the side load pin L2 and associated wiring. If no faults are
found proceed to next step.
7.14.2 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 #4
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 #5 terminal at the black P2 connector. The
meter should read 2.5 +/- .2 VDC with the right joystick in the centered
position. If no voltage is present, replace the side load pin L2. If voltage
is present, move the meter ground lead to terminal #6 of the black P2
connector. Move the red meter lead to terminal #4 of the black P2
connector. The meter should read battery voltage. If no voltage is
present, keep the black meter lead inserted in terminal #6 and move
the red meter lead to the alternator battery terminal. The meter should
read battery voltage. If voltage is present, replace the side load pin L2.
If no voltage is present, replace the control board.
7.14.3 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.
