1.CHECK POWER STEERING SOLENOID VALVE SIGNAL

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

Is the inspection result normal?
YES>>GO TO 4.
NO>>GO TO 2.
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.

   Power steering solenoid valve | Power steering control unit | Continuity
   Connector | Terminal | Connector | Terminal
   E207 | 1 | M108 | 1 | Existed
   2 | 5 | Existed

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

   Power steering control unit | — | Continuity
   Connector | Terminal
   M108 | 1 | Ground | Not existed
   5

Is the inspection result normal?
YES >>GO TO 3.
NO>>Repair or replace error-detected parts.
3.CHECK POWER STEERING SOLENOID VALVE
Check the power steering solenoid valve. Refer to Component Inspection (GT-R certified NISSAN dealer).
Is the inspection result normal?
YES >>GO TO 4.
NO>>Replace gear-sub assembly. Refer to Exploded View.
4.CHECK TERMINALS AND HARNESS CONNECTORS

- 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.

Is the inspection result normal?
YES>>INSPECTION END
NO>>Repair or replace error-detected parts.
