Switch - Mode Selection
Illustration 2 g03377676
The mode selection switch is a three position switch with an AUTOMATIC position, MANUAL position, and OFF position. When the mode selection switch is moved to the AUTOMATIC position, a ground signal is supplied to the Power Train ECM. With the parking brake disengaged, the Power Train ECM changes the seat position based on the position of the transmission direction control switch. Refer to Table 1 for transmission direction control switch position versus seat movement.

Gear Selected     Current Seat Position     New Seat Position    
FORWARD to REVERSE     FORWARD     REVERSE    
FORWARD to NEUTRAL     FORWARD     FORWARD (1)    
REVERSE to NEUTRAL     REVERSE     REVERSE (1)    
REVERSE to FORWARD     REVERSE     FORWARD    
( 1 ) No changeNote: When the parking brake is engaged, the seat will no longer follow the position of the transmission direction control switch.When the mode selection switch is moved to the MANUAL position, a ground signal is supplied to the Power Train ECM. Seat movement no longer responds to the position of the transmission direction control switch. Seat movement will now only respond to the manual swivel switch when machine speed is less than 10 km/h (6 mph).When the mode selection switch is moved to the OFF position, a ground signal is supplied to the Power Train ECM. The seat will not move until the manual swivel switch is pressed and released. Pressing and releasing the manual swivel switch within 5 seconds and moving the mode selection switch to the OFF position, will cause the Power Train ECM to move the seat to the center position. The seat will no longer move regardless of the manual swivel switch being pressed.Switch - Speed Selection
Illustration 3 g03377676
The speed selection switch is a three position switch with a SLOW position, MEDIUM position, and HIGH position. When the speed selection switch is turned to the SLOW, MEDIUM, or HIGH position, a ground signal is supplied to the Power Train ECM. The Power Train ECM will energize the control solenoid valve proportional to the speed selector switch position.Note: Each speed setting will have a separate acceleration, deceleration, and maximum speed.Switch - Swivel
Illustration 4 g03378198
When the manual swivel switch is pressed and released, a ground signal is sent to the Power Train ECM. The Power Train ECM will energize the directional solenoid valve for forward or reverse movement based on an input from the seat position sensor. Machine speed must be less than 5 km/h (3 mph).Switch - Transmission Neutralizer Override
Illustration 5 g03377677
The transmission neutralizer override switch is a two position switch with an ON position and an OFF position.When the transmission neutralizer override switch is moved down to the ON position, a ground signal is supplied to the Power Train ECM. When the Power Train ECM receives a signal from the service brake pressure sensor and machine ground speed is less than 5 km/h (3 mph), the Power Train ECM will neutralize the transmission.When the transmission neutralizer override
