Component Function Check

Check disconnection, looseness or improper connection of hose between turbocharger boost control solenoid valve and boost control actuator.

Is the inspection result normal? 

YES: GO TO 2.

NO: Proceed to "DIAGNOSIS PROCEDURE ".

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 outlet pipe.
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 [73 kPa (730 mbar, 548 mmHg, 21.56 inHg)] with battery voltage to terminals 1 and 2	Boost control actuator rod operates
   Supply pressure [73 kPa (730 mbar, 548 mmHg, 21.56 inHg)] without battery voltage to terminals 1 and 2	Boost control actuator rod not operates

   CAUTION: Do not supply pressure over 83 kPa (830 mbar, 623 mmHg, 24.51 inHg)

   Is the inspection result normal? 

   YES: INSPECTION END

   NO: Proceed to "DIAGNOSIS PROCEDURE ".
