INSPECTION PROCEDURE

 

1.INSPECT VRV FOR TURBOCHARGER CONTROL

 

1. Disconnect the B44 VRV connector.

2. Measure the resistance of the VRV.

    

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   B44-1 - B44-2	20°C (68°F)	11.1 to 12.5 Ω

    

    

3. Reconnect the VRV connector.

 

NG	REPLACE VRV FOR TURBOCHARGER CONTROL

OK

 

2.INSPECT VRV FOR TURBOCHARGER CONTROL (TERMINAL 1 VOLTAGE)

 

1. Disconnect the B44 VRV connector.

2. Turn the ignition switch on (IG).

3. Measure the voltage of the VRV connector.

    

   Standard voltage:

   Tester Connection	Specified Condition
   B44-1 - Body ground	9 to 14 V

    

    

4. Reconnect the VRV connector.

 

NG	CHECK WIRE HARNESS (VRV - EFI MAIN RELAY)

OK

 

3.CHECK WIRE HARNESS (VRV - ECM)

 

1. Disconnect the B44 VRV connector.

2. Disconnect the B32 ECM connector.

3. Measure the resistance of the wire harness connector.

    

   Standard resistance:

   Tester Connection	Specified Condition
   B44-2 - B32-84 (VN)	Below 1 Ω
   B44-2 or B32-84 (VN) - Body ground	10 kΩ or higher

    

    

4. Reconnect the VRV connector.

5. Reconnect the ECM connector.

 

NG	REPAIR OR REPLACE HARNESS AND CONNECTOR

OK
REPLACE ECM
