Throttle-Up Switch

1. Remove the side cover.

2. Disconnect the 

2P

 connector of throttle-up switch (1).

3. Measure  the  continuity  with  an  ohmmeter  across  the  switch

terminals.

4. If it does not conduct or any value is indicated when the switch

is pushed, the switch is faulty.

5. If infinity is not indicated when the switch is released, the switch

is faulty.

HST Proportional Valve (Forward and Reverse)

1. Remove the cover.

2. Disconnect the 

2P

 connector of the proportional valve (1), (2).

IMPORTANT

• In installing the connector of the proportional valve, pay

attention to the color of the connector to ensure correct
installation.

3. Measure the resistance between terminal 

1

 (3) and 

2

 (4).

4. It  is  OK  if  the  resistance  comes  to  have  shown  in  the  table

below.

NOTE

• When replacing the sensor, be sure to adjust the mode "K".
