7.12 Error Code 211 - Right Load Pin Open Circuit
7.12.1 Check the right load pin L1 wire connections. Perform a visual
inspection of the right load pin L1 and associated wiring. If no faults are
found proceed to next step.
7.12.2 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 #1
terminal at the black P2 connector. The meter should read that there
is battery voltage. If no voltage is present, replace the control board. If
voltage is present, back probe the #2 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 right load
pin L1. If voltage is present, move the meter ground lead to terminal #3
of the black P2 connector. Move the red meter lead to terminal #1 of
the black P2 connector. The meter should read battery voltage. If no
voltage is present, keep the black meter lead inserted in terminal #3
and move the red meter lead to the alternator battery terminal. The
meter should read battery voltage. If voltage is present, replace the
right load pin L1. If no voltage is present, replace the control board.
7.12.3 After replacing the failed component be sure to reposition the wiring
harnesses in the correct configuration and retain the harnesses. Turn
the ignition switch to ON and test the functionality of all 3 circuits: right,
left, and side.
7.13 Error Code 212 - Right Load Pin Short Circuit
7.13.1 Check the right load pin L1 wire connections. Perform a visual
inspection of the right load pin L1 and associated wiring. If no faults are
found proceed to next step.
7.13.2 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 #1
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 #2 terminal at the black P2 connector. The
meter should read 2.5 +/- .2 VDC with the right joystick in the centered
position. If the meter reads over 2.5 +/- .2 VDC, replace the right load
pin L1. If the correct 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, proceed to next step.
