Functional Check
1. Apply battery voltage across the terminals a and c, and check
for continuity across the terminals d and e.
2. If continuity is not established across terminals d and e, replace
it.

[10] SOLENOID VALVE
Solenoid Valves
1) Connector Voltage
1. Remove the connector (1).
2. Turn on the main switch, PTO switch or 4WD switch at ON
position.
3. Measure the voltage across the each terminal and chassis.
4. If the voltage differs from battery voltage, the wiring harness,
fuse or main switch is faulty.
2) Solenoid Valve
1. Disconnect the wire harness connector (1).
2. Measure the resistance with an ohmmeter across the each
terminal 1/3 on the connector (1) and chassis.
3. If infinity is indicated, the solenoid valve is faulty.
