With Rear Active Steer

POWER STEERING SOLENOID VALVE





Description
The power steering oil pressure in the gear housing assembly is controlled.




Diagnosis Procedure
1.CHECK POWER STEERING SOLENOID VALVE SIGNAL

With CONSULT-III
1. Start the engine.
2. Select "DATA MONITOR" of "4WAS(MAIN)/RAS/HICAS".
3. Check "POWER STR SOL" item on "DATA MONITOR" of RAS control unit.






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





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





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





Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace the harnesses and connectors.
3.CHECK POWER STEERING SOLENOID VALVE
Check the power steering solenoid valve. SEE Component Inspection.
Is the inspection result normal?
YES - INSPECTION END
NO - Repair the steering gear. Exploded View.




Component Inspection
1.POWER STEERING SOLENOID VALVE INSPECTION
1. Turn the ignition switch OFF.
2. Disconnect the power steering solenoid valve harness connector.
3. Check the resistance between power steering solenoid valve connector terminals.





4. 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. Exploded View.
