7.21 Error Code 322 - Left Joystick Short Circuit
7.21.1 Check the left joystick wire connections. Perform a visual inspection of
the left joystick and associated wiring. If no faults are found proceed to
next step.
7.21.2 Use a digital volt/ohm meter to test for voltage at the gray P1 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 gray P1 connector. The meter should read 5 VDC. If no
voltage is present, replace the control board. If voltage is present, back
probe the #8 terminal at the gray P1 connector. The meter should read
2.5 +/- .2 VDC with the left joystick in the centered position. If the meter
reads over 2.5 +/- .2 VDC, replace the left joystick. If the correct
voltage is present, insert the red meter lead in terminal #10 of the gray
P1 connector. The meter should read 0 VDC. If voltage is present,
proceed to next step.
7.21.3 Turn ignition switch OFF. Remove the gray P1 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 #10 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 #10. If voltage is present,
replace the left joystick. If no voltage is present, insert the red meter
lead in terminal #10 of the gray P1 connector. The meter should read
0 VDC. If voltage is present, replace the control board. Be sure to
reinstall terminal #5 into the gray P1 connector, reverse the removal
procedure to install.
7.21.4 After replacing the failed component make sure to reposition the wiring
harnesses in the correct configuration and secure with wire ties. Turn
the ignition switch to ON and test the functionality of all 3 circuits; right,
left, and side.
