do so, turn the ignition switch ON, connect the black lead of a

multimeter to a common ground, and back probe the #7 terminal of the

P1 connector with the red lead of the multimeter.The multimeter should

read approximately 5.0V.

• If no voltage is measured, the control board has failed; replace it.

• If the proper voltage is measured,continue.

joystick at the P1 control board connector. To do so, turn the ignition

switch ON, connect the black lead of the multimeter to a common

ground, and back probe the #8 terminal of the P1 connector. With the

left joystick in the centered position, 2.5±0.2 Volts should be

measured.

• If no voltage is measured, the left joystick has failed; replace it.

• If the proper voltage is measured, continue.
