Without Rear Active Steer

POWER STEERING SOLENOID VALVE

Description
Power steering solenoid valve controls the power steering oil pressure in the gear housing assembly.

Diagnosis Procedure
1.CHECK POWER STEERING SOLENOID VALVE SIGNAL
1. Turn the ignition switch OFF.
2. Check voltage between power steering control unit harness connector and ground.

Is the inspection result normal?
YES - GO TO 2.
NO - GO TO 4.
2.CHECK HARNESS BETWEEN POWER STEERING SOLENOID VALVE AND POWER STEERING CONTROL UNIT
1. Turn the ignition switch OFF.
2. Disconnect power steering solenoid valve harness connector.
3. Disconnect power steering control unit harness connector.
4. Check the continuity between power steering solenoid valve harness connector and the power steering control unit harness connector.

5. Check continuity between power steering control unit harness connector and ground.

Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace damaged parts.
3.CHECK POWER STEERING SOLENOID VALVE
Check power steering solenoid valve. SEE Component Inspection.
Is the inspection result normal?
YES - GO TO 4.
NO - Replace gear-sub assembly. Exploded View.
4.CHECK TERMINALS AND HARNESS CONNECTORS
- Check power steering control unit pin terminals for damage or loose connection with harness connector.
- Check power steering solenoid valve pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES - INSPECTION END
NO - Repair or replace damaged parts.

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

4. Check power steering solenoid valve by listening for its operation sound while applying battery voltage to power steering solenoid valve connector F45 terminals 1 (positive) and 2 (negative).
Is the inspection result normal?
YES - INSPECTION END
NO - Replace gear-sub assembly. Exploded View.
