POWER STEERING SOLENOID VALVE

1. Turn the ignition switch OFF.
2. Check the voltage between power steering control unit harness connector and ground.
   

   Power steering control unit		—	Condition		Voltage (Approx.)
   Connector	Terminal
   M108	1	Ground	Vehicle speed: 0 km/h (0 MPH) (Engine is running)		4.4 – 6.6 V
   			Vehicle speed: 100 km/h (62 MPH)		2.4 – 3.6 V

   
   

YES>>GO TO 2.

NO>>GO TO 4.

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.

YES >>GO TO 3.

NO>>Repair or replace error-detected parts.

Check the power steering solenoid valve. Refer to Component Inspection (GT-R certified NISSAN dealer).

YES >>GO TO 4.

NO>>Replace gear-sub assembly. Refer to Exploded View.

• Check the power steering control unit pin terminals for damage or loose connection with harness connector.
• Check the power steering solenoid valve pin terminals for damage or loose connection with harness connector.

YES>>INSPECTION END

NO>>Repair or replace error-detected parts.

1. Turn the ignition switch OFF.
2. Disconnect power steering solenoid valve harness connector.
3. Check resistance between power steering solenoid valve connector terminals.
   

   Power steering solenoid valve			Resistance (Approx.)
   Connector	Terminal
   E207	1	2	4 – 6 Ω

   
   
4. Check power steering solenoid valve by listening for its operation sound while applying battery voltage to power steering solenoid valve connector E207 terminals 1 (positive) and 2 (negative).
