DESCRIPTION

УКАЗАНИЕ:

1. Specified values in the following troubleshooting flowchart are for reference only. Variations in the Data List values may occur depending on the measuring conditions or the vehicle's age. Do not judge the vehicle to be normal even when the Data List values indicate a standard level. There are possibly some concealed factors of the malfunction.
   
2. Check that the vehicle has not been modified in any way prior to the vehicle inspection.
   
3. This troubleshooting procedure checks for the cause of an obvious lack of engine power (the vehicle speed does not reach the target speed in the high speed range) while the vehicle is being driven.

УКАЗАНИЕ:

By performing this Active Test, the engine speed is maintained at 2000 rpm and the common rail internal fuel pressure is raised to the maximum operating pressure. As a result, a fuel leak check can be conducted while retaining the high common rail pressure.

2. Start the engine and turn the tester on.
   

3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Test the Fuel Leak.
   

4. Visually check the supply pump, injector and fuel line located between the supply pump and common rail for fuel leaks and fuel pressure leaks. Also, perform the same check on the fuel line between the common rail and the injector.
   

   УКАЗАНИЕ:

   There may be fuel leaks inside the components, such as the supply pump.

1. Follow the instructions in the table below according to the check result of the intelligent tester.
   

   УКАЗАНИЕ:

   This operation is based on the premise that the common rail pressure is normal.

   
   

   Standard value:

   
   

   Item	Engine Speed*	Reference Value
   Injection Feedback Val #1 to #4	Idling	-3.5 to 3.5 mm3
   Injection Volume	Idling	2.8 to 7.3 mm3

   УКАЗАНИЕ:

   *: The air conditioner switch and all accessory switches should be OFF, and the engine should be fully warmed up.

   
   

   Result:

   
   

   Injection Volume	Injection Volume
   Injection Feedback Val #1 to #4	Less than 2.8 mm3	Between 2.8 and 7.3 mm3 (Normal)	More than 7.3 mm3
   3.5 mm3 or more, -3.5 mm3 or less	A	B	B
   Between -3.5 and 3.5 mm3	-	Normal	C*

   
   

   Proceed to	Inspection Area	Descriptions
   A	Inspect and repair cylinder injector with revised injection volume of less than -3.5 mm3: Perform power balance inspection and identify malfunctioning cylinder Replace malfunctioning cylinder injector	Abnormal value cylinder injector injects excessively large quantity of fuel
   B	Identify malfunctioning cylinders by conducting power balance inspection: Perform power balance inspection to identify malfunctioning cylinders Clean malfunctioning cylinder injector, check, and repair it	Abnormal value cylinder injector injects excessively small quantity of fuel: Fuel injection volume too low due to injector nozzle being blocked by deposits Abnormal value cylinder injector compression decreases Abnormal value cylinder injector injects excessively large quantity of fuel
   C	Inspect and repair all cylinder injectors: Clean all cylinder injectors, inspect, and repair them	All cylinder injectors inject excessively small quantity of fuel: Fuel injection volume too low due to all cylinder injector nozzles being blocked by deposits

   УКАЗАНИЕ:

   *: When the Injection Volume displayed on the tester is large despite the Fuel Pressure and Injection Feedback Val #1 to #4 in the Data List being normal, the injector may be clogged. In this case, there may be deposits inside or outside the tip of the injector.

   1. Despite the injector functioning normally, the indicated Injection Feedback Val #1 to #4 value may be outside the normal operating range due to compensation for other problems (such as low compression).
      
   2. Injection Feedback Val #1 to #4 is the value used to correct the fuel injection volumes of each cylinder, in order to optimize (compensate for the unevenness between) all the cylinder combustion conditions. If any of the cylinders malfunction, the fuel injection volumes for the normal cylinders are corrected simultaneously. As a result, the Injection Feedback Val #1 to #4 may deviate from the standard range.
