(C) Checking Sensor and Switch
IntelliPanel and ECU Continuity
1. Disconnect the connector B (16P) from IntelliPanel. (See page
9-S23.)
2. Measure the resistance between terminal 4 of panel connector
and terminal 21 of ECU connector, and between terminal 5 of
panel connector and terminal 43.
3. If 0 Ω is not indicated, the wiring harness is faulty.

GST Lever Sensor Resistance
1. Measure the resistance between terminal a and c when the shaft
is fully turned left.
2. Then, check resistance between terminal a and b while slowly
turning the sensor shaft.
3. It is OK if the resistance value approximates to the value shown
in the table below.
(Reference)
• The change of resistance can be checking easily when an analog
tester is employed.

Terminal a - Terminal b
Pressure Switch Resistance
1. Disconnect the pressure switch connector (1).
2. Connect the circuit tester pins to each terminal of pressure switch
(2).
3. Start the engine and depress the clutch pedal.
4. Check the resistance at time when shuttle lever or GST lever is
shifted.
5. It is OK if the resistance comes to have shown in the table below.
CAUTION
• Be sure to depress the clutch pedal so that the tractor
should not move while shifting each lever.
