УКАЗАНИЕ:

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.
Check that the vehicle has not been modified in any way prior to the vehicle inspection.
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.

INSPECTION PROCEDURE

ПРИМЕЧАНИЕ:

After replacing the supply pump, the ECM needs initialization (see page RAV4_ACA30 RM000000TIN007X.html).
After replacing the injector, the ECM needs registration (see page RAV4_ACA30 RM000000TJ4007X.html).

УКАЗАНИЕ:

Before troubleshooting, conduct the following:

Check the fuel quality.
Check the fuel for air.
Check the fuel system for blockages.
Check the air filter.
Check the engine oil.
Check the engine coolant.
Check the engine idling speed and the maximum engine speed.
Check the vacuum pump.

1.CHECK WIRE HARNESS AND CONNECTOR IN ENGINE ROOM

Check the wire harness and connector connections of common rail system components.
УКАЗАНИЕ:
Check the following components and system:
1. Sensors
2. Supply pump
3. Common rail
4. Injectors
5. EDU
6. Turbocharger system
7. Intake and exhaust system
OK:
The wire harnesses and connectors are connected securely.

REPAIR OR REPLACE HARNESS AND CONNECTOR

OK

2.PERFORM CONFIRMATION DRIVING PATTERN

УКАЗАНИЕ:

Drive the vehicle according to the driving pattern below to allow the ECM to set DTCs relating to malfunctions of the fuel system, EGR system, and throttle valve. If DTCs are set, problem areas can be identified.

Start the engine (procedure "A").

Stop the engine and wait for at least 10 seconds (procedure "B").

Perform procedure "A" and procedure "B" again described above to allow the ECM to set pressure discharge valve malfunction DTCs.

Enter CHECK MODE (see page RAV4_ACA30 RM000000TIJ007X.html).

Fully warm up the engine.

Allow the engine to idle for 5 minutes or more.

Drive the vehicle at more than 40 km/h (25 mph) for 1 minute or more (procedure "C").

Decelerate and stop the vehicle (procedure "D").

Repeat procedure "C" and procedure "D" 4 times or more.

Stop the engine and wait for at least 10 seconds (procedure "E").

Repeat procedure "C" and procedure "E" described above to set DTCs relating to the EGR system and throttle valve.

Drive the vehicle at more than 70 km/h (43 mph) for at least 1 minute (to set DTCs relating to the supply pump).

4.PERFORM ACTIVE TEST BY INTELLIGENT TESTER (TEST THE FUEL LEAK)

УКАЗАНИЕ:

By performing this Active Test, the engine speed is maintained at 2,000 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.

Connect the intelligent tester to the DLC3.

Start the engine and turn the tester ON.

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

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.
OK:

5.CHECK WHITE SMOKE

Rev up the engine from idling to 3,000 rpm several times to check whether white smoke is emitted from the exhaust pipe.

Check that the intake system pipes and hoses are not excessively contaminated with oil.
If white smoke is emitted from the intake system, its pipes and hoses are excessively contaminated with oil. If the presence of white smoke in the exhaust gas is confirmed, there is a high possibility of mechanical problems in the turbocharger or engine.

14.IDENTIFY MALFUNCTIONING CYLINDER INJECTOR

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	-3.0 to 3.0 mm³
Injection Volume	Idling	3.9 to 7.0mm³

УКАЗАНИЕ:

*: The A/C 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 3.9 mm³	Between 3.9 to 7.0 mm³ (Normal)	More than 7.0 mm³
3.0 mm³ or more, -3.0 mm³ or less	A	B	B
Between -3.0 to 3.0 mm³	-	Normal	C*

Proceed to	Proceed to	Descriptions
A	Inspect and repair cylinder injector with revised injection volume of less than -3.0 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.

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).
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.
