1.CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.
2. Disconnect turbocharger boost control solenoid valve harness connector.
3. Turn ignition switch ON.
4. Check the voltage between turbocharger boost control solenoid valve harness connector and ground.

   Turbocharger boost control solenoid valve | Ground | Voltage
   Connector | Terminal
   F34 | 1 | Ground | Battery voltage

Is the inspection result normal?
YES>>GO TO 3.
NO>>GO TO 2.
2.DETECT MALFUNCTIONING PART
Check the following.

- Harness connectors E3, F1
- Harness for open or short between turbocharger boost control solenoid valve and IPDM E/R

>>Repair open circuit, short to ground or short to power in harness or connectors.
3.CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between turbocharger boost control solenoid valve harness connector and ECM harness connector.

   Turbocharger boost control solenoid valve | ECM | Continuity
   Connector | Terminal | Connector | Terminal
   F34 | 2 | F102 | 61 | Existed

4. Also check harness for short to ground and short to power.

Is the inspection result normal?
YES>>GO TO 4.
NO>>Repair open circuit, short to ground or short to power in harness or connectors.
4.CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE
Refer to Component Inspection (GT-R certified NISSAN dealer).
Is the inspection result normal?
YES>>GO TO 5.
NO>>Replace turbocharger boost control solenoid valve.
5.CHECK INTERMITTENT INCIDENT
Refer to Intermittent Incident.
