1. 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.

2. Connect the pressurized type hand vacuum pump with the

three-way joint.

3. 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.
4. Blocking or releasing the boost hose end, apply the

pressure. Check the pressurized state.
