- Removing the black hose from the No.1 turbocharger wastegate solenoid or the brown connector, connect three-way joint between the hose and the solenoid.
- Connect the pressurized type hand vacuum pump with the three-way joint.
- Use the turbocharger wastegate actuator control boost nipple of air outlet fitting to remove the boost hose. Plug this nipple.CAUTION: Do not apply the pressure of 117kPA or more to prevent the diaphragm damage.
- Blocking or releasing the boost hose end, apply the pressure. Check the pressurized state.IGNITION SWITCH POSITION CHART
