DESCRIPTION OF THE GEAR SELECTOR 
SYSTEM:   

1.1.

The gear selector on the 4 X 2 Utility Vehicle is 
electronically controlled and vacuum actuated. 
The operator selects the desired gear by push-
ing one of 

three buttons on the dashboard

.  

The operator engages and disengages the dif-
ferential lock using a yellow button to the left of 
the steering wheel. See Figure 1.1.

     

1.2.

A corresponding light on the 

instrument panel

 

confirms the selection, or flashes a trouble code 
in the event of a malfunction. See Figure 1.2.

1.3.

The 

brake switch

 is tied into the gear selector 

circuitry. The vehicle will not shift gears if the 
brake pedal is not depressed far enough to actu-
ate the switch or if the switch actuator is out of 
adjustment. See Figure 1.3.

1.4.

The 

neutral switch

, mounted on the transaxle, 

above the Shift Wedge, confirms the position of 
the shift wedge. A detent in the 

shift wedge

 

moves a contact roller in the neutral sensor 
when the shift wedge moves, generating a signal 
that goes to the electronic shift module (ESM).      
See Figure 1.4.
