(3) Checking Sensor and Switch for GST Model
GST Lever Sensor Resistance
1. Measure the resistance between terminal a (1) and c (3).
2. Then, check resistance between terminal a (1) and b (2) while
slowly turning the sensor shaft.
3. It is OK if the resistance value approximates to the value shown
in the table below.
• When replacing the sensor, be sure to adjust the mode "E".
(Reference)
• The change of resistance can be checking easily when an
analog tester is employed.

Pressure Switch Resistance
1. Disconnect the pressure switch connector (1).
2. Connect the circuit tester pins to each terminal of pressure
switch (2).
3. Check the resistance between the terminals when the engine is
not started.
4. Start the engine and depress the clutch pedal.
5. Check the resistance between the terminals when the engine is
started.
6. It is OK if the resistance comes to have the value shown in the
table below.
• It is not necessary to adjust any kind of mode.
• Be sure to depress the clutch pedal so that the tractor
should not move while shifting each lever.

Oil Temperature Sensor Resistance
1. Measure the resistance between the sensor terminals.
2. It is OK if the resistance value approximates to the value shown
in the table below.
3. If the exists a large difference, replace the sensor.
• It is not necessary to adjust any kind of mode.
