1.PERFORM COMPONENT FUNCTION CHECK-I Check the following.

- Disconnection of air duct or hose between electric throttle control actuator and compressor wheel.
- Exhaust gas leaks of exhaust manifold
- Open stuck of recirculation valve
- Stuck of turbocharger

Is the inspection result normal?
YES>>GO TO 2.
NO>>Go to Diagnosis Procedure (GT-R certified NISSAN dealer).
2.PERFORM COMPONENT FUNCTION CHECK-II

1. Turn ignition switch OFF.
2. Disconnect turbocharger boost control solenoid valve harness connector.
3. Disconnect of hose between turbocharger boost control solenoid valve and compressor wheel.
4. Install pressure pump to turbocharger boost control solenoid valve.
5. Check that the rod of the boost control actuator activates when supplying pressure and battery voltage to the turbocharger boost control solenoid valve as per the following conditions.

   Turbocharger boost control solenoid valve | Operation
   Condition
   Supply pressure [60 kPa (450 mmHg, 17.72 inHg)] with battery voltage to terminals 1 and 2 | Boost control actuator rod operates
   Supply pressure [60 kPa (450 mmHg, 17.72 inHg)] without battery voltage to terminals 1 and 2 | Boost control actuator rod not operates

   ■ CAUTION ■
   Do not supply pressure over 70 kPa (525 mmHg, 20.67 inHg).

   1. | Boost control actuator (bank 1) | 2. | Turbocharger boost control solenoid valve | 3. | Boost control actuator (bank 2)
   A. | Pressure pump |  |  |  |
   | : Vehicle front |  |  |  |

Is the inspection result normal?
YES>>INSPECTION END
NO>>Go to Diagnosis Procedure (GT-R certified NISSAN dealer).
