7.19 Error Code 312 - Right Joystick Short Circuit
7.19.1 Check the right joystick wire connections. Perform a visual inspection
of the right joystick and associated wiring. If no faults are found
proceed to next step.
7.19.2 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 #2
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 #3 terminal at the gray P1 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 joystick. If the correct
voltage is present, back probe the #4 terminal at the gray P1
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 joystick. If the correct voltage is present, insert the red meter
lead in terminal #5 of the gray P1 connector. The meter should read 0
VDC. If voltage is present, proceed to next step.
7.19.3 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 #5 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 #5. There should be no voltage present.
If voltage is present, replace the right joystick. If no voltage is present,
insert the red meter lead in terminal #5 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.
7.19.4 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.
