POWER STEERING SOLENOID VALVE


Diagnosis Procedure

1.CHECK POWER STEERING SOLENOID VALVE SIGNAL

With CONSULT-III
1. Start the engine.
2. Check "POWER STR SOL" item on "DATA MONITOR" of 4WAS main control unit.






Without CONSULT-III
1. Start the engine.
2. Check the voltage between 4WAS main control unit harness connector and the ground.





3. Check that there is no malfunction in 4WAS main control unit harness connector or disconnection.
Is the inspection result normal?
YES - GO TO 2.
NO - Replace 4WAS main control unit. Refer to Exploded View.
2.CHECK POWER STEERING SOLENOID VALVE CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect 4WAS main control unit harness connector.
3. Disconnect the power steering solenoid valve harness connector.
4. Check the continuity between 4WAS main control unit harness connector and power steering solenoid valve harness connector.





5. Check the continuity between power steering solenoid valve harness connector and the ground.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace the harnesses and connectors.
3.CHECK POWER STEERING SOLENOID VALVE
1. Check the resistance between power steering solenoid valve connector terminals.





2. Check for click sound (power steering solenoid valve activation sound) when applying approximately 12 V between the power steering solenoid valve connector terminals.

CAUTION:
- Never make the terminals short.
- Assign the positive terminal to No. 1 terminal, and the negative terminal to No. 2 terminal. Connect the fuse between the terminals when applying the voltage.
Is the inspection result normal?
YES - INSPECTION END
NO - Repair the steering gear.
