7.22.7 Check the joystick ground wire. To do so, disconnect the wiring

harness at P1. Remove the orange locking plug (a) from the front of

the connector. Use a small screwdriver to release the locking tab and

remove the black wire from terminal #6. Isolate the black wire from all

metal surfaces. Reinstall the orange locking plug and reconnect the

connector to the control board at P1. Turn the ignition ON and check

for voltage between the black wire and ground. There should be no

voltage.

• If voltage is measured, the joystick has failed; replace it.

• If no voltage is measured, continue.

7.22.8 With the black wire still disconnected, check the control board for a

voltage leak. Probe the #6 terminal of the P1 connector with the red

lead, and probe a common ground with the black lead.

• If voltage is measured, the control board has failed; replace it.

• If no voltage is measured, the system should be OK. Reconnect

the wire to terminal #6 of the connector.

7.22.9 After replacing any failed component, make sure to reposition the

wiring harness in the correct configuration and secure it with wire ties.

Turn the ignition switch ON and test the function of all three circuits:

right, left, and side.
