DATA LIST

Tech Tips

Using the intelligent tester to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

Note

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Warm up the engine.
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Start the engine.
Turn the intelligent tester on.

Calculate Load
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
Calculate Load	Load calculated by ECM/ Min.: 0%, Max.: 100%	Idling: 7 to 26% Running without load (2500 rpm): 10 to 20%	Calculated by ECM	Malfunction in which turbo pressure or Mass Air Flow decreases
Calculate Load	Diagnostic Note: Calculated load = (Final injection volume / max. injection volume at current engine speed) x 100.

MAF
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
MAF	Air flow rate from mass air flow meter/ Min.: 0 g/sec., Max.: 400 g/sec.	Idling: 5 to 12 g/sec. Running without load (2000 rpm): 15 to 35 g/sec. Tech Tips Depends on EGR rate	Sensor output (mass air flow meter)	Mass air flow meter Mass air flow meter circuit Intake related clog or leak Exhaust related clog Turbocharger sub-assembly Leak or clog in passages for turbocharger Malfunction in which EGR valve does not close
	Symptoms when out of range: Rough idling
	Diagnostic Note: Based on the MAF, the ECM controls the fuel injection volume, injection timing, EGR, etc. If the value is always approximately 0 g/sec.: Mass air flow meter power source circuit is open. VG circuit is open or shorted. EVG circuit is open.

Atmosphere Pressure
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
Atmosphere Pressure	Atmospheric pressure value/ Min.: 50 kPa, Max.: 120 kPa	Actual atmospheric pressure	Sensor output (atmospheric pressure sensor (built into ECM))	Atmospheric pressure sensor itself has failed (atmospheric pressure sensor is inside the ECM)
	Symptoms when out of range: -
	Diagnostic Note: With the ignition switch ON, when the difference between the atmospheric pressure sensor and intake manifold absolute pressure is 10 kPa or more, there is a malfunction in one of the sensors. With the ignition switch ON, when the atmospheric pressure is 0 kPa or 140 kPa, there is a malfunction in the sensor circuit. Standard atmospheric pressure: 101 kPa. For every 100 m increase in elevation, pressure drops by 1 kPa. This varies by weather (high atmospheric pressure, low atmospheric pressure).

MAP
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
MAP	Absolute pressure inside intake manifold/ Min.: 0 kPa, Max.: 255 kPa	Idling: 94 to 104 kPa (depending on barometric pressure) Engine running at 3000 rpm: 100 to 150 kPa	Sensor output (manifold absolute pressure sensor)	Manifold absolute pressure sensor Intake related clog or leak Exhaust related clog Turbocharger sub-assembly Leak or clog in passages for turbocharger EGR valve stuck open Exhaust leak Throttle valve stuck closed
	Symptoms when out of range: Lack of power
	Diagnostic Note: When the ignition switch is ON or the vehicle is idling, the intake manifold absolute pressure and atmospheric pressure are approximately the same (standard atmospheric pressure = 101 kPa). Above approximately 1500 rpm, the turbo becomes effective and the pressure becomes higher than atmospheric pressure. Inspect while comparing with "Target Booster Pressure". With the accelerator fully open, if the actual manifold absolute pressure (MAP) is low compared to the target booster pressure by at least 20 kPa for 5 seconds or more, a feeling of insufficient power will occur.

Battery Voltage
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
Battery Voltage	Battery voltage/ Min.: 0 V, Max.: 15 V	11 to 14 V	-	-
	Symptoms when out of range: If 5 V or less, starting becomes difficult
	Diagnostic Note: If 11 V or less, characteristics of some electrical components change.

Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
Alternate Duty Ratio	Alternator generation duty ratio/ Min.: 0%, Max.: 100%	No electrical load at idling: 20 to 60% High electrical load at idling: 100%	Duty value from ALT terminal	Battery deterioration Alternator malfunction Electric load, lights, etc.
Alternate Duty Ratio	Diagnostic Note: This is outputs the alternator generation duty and is used to determine the electrical load. Can be used to determine whether a higher-than-normal injection volume at idle, etc. is due to electrical loading or from some other source. For example, when the duty is not high but the idling injection volume is high, there is injector volume degradation or high engine friction. Can be used for judging whether or not a malfunctioning component in the electrical system is generating continual generation requests (e.g., battery deterioration is causing an unending full recharge request, etc.). Regardless of whether or not an auxiliary device like the A/C or heater is active, if the alternator duty is always at the maximum value, there is an electrical system abnormality, like battery deterioration.

Accel Position	Accelerator position status/ Min.: 0%, Max.: 100%	Accelerator pedal released: 0% Accelerator pedal fully depressed: 100%	Accelerator pedal position sensor opening position ECT requested opening position Cruise requested opening position VSC requested opening position	-
Accel Position	Diagnostic Note: "Accel Position" is the accelerator opening amount (%) for engine control use. When the accelerator pedal position sensor output itself (Accelerator Position 1, Accelerator Position 2) is in the normal voltage range, another actuator malfunction has caused the fail-safe function to restrict the accelerator. Without cruise, ECT or VSC requests, and without accelerator restriction by the fail-safe function, this is adjusted in proportion to the amount the accelerator pedal is depressed by the driver. Accelerator pedal released: 0% Accelerator pedal fully depressed: 100%

Tech Tips

Accel Sens. No.1 Volt % and Accel Sens. No.2 Volt % express the value obtained by dividing the output voltage from the accelerator pedal position sensor by 5. This is used only for diagnosing malfunctions in the accelerator pedal position sensor. Under normal conditions, it is sufficient to only check the final accelerator opening angle value "Accel Position".

Common Rail Pressure
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
Common Rail Pressure	Fuel pressure/ Min.: 0 kPa, Max.: 250000 kPa	Idling: 30000 to 40000 kPa	Sensor output (fuel pressure sensor)	Fuel supply pump assembly High pressure pipes Fuel pressure sensor Injector assembly Feed pump (fuel supply pump assembly) Fuel filter element sub-assembly Pressure limiter Air in the fuel pipes Lack of fuel
	Symptoms when out of range: Difficult to start, poor driveability, lack of power, abnormal combustion noise
	Diagnostic Note: Common rail pressure is the actual common rail fuel pressure. Inspect by comparing the fuel pressure with the target fuel pressure. When in a stable condition such as when idling, the fuel pressure is within +/-5000 kPa of the target fuel pressure. The ECM uses fuel pressure for feedback control of the target fuel pressure via the supply pump. The injection amount is determined based on the injection timing and fuel pressure. Also, the spray pattern is selected based on the fuel pressure. For startup, at least 25000 kPa of fuel pressure is needed (take care as there is a response lag when the pressure rises). When the fuel pressure is below 25000 kPa, it may cause rough idling. When the fuel pressure has decreased by 20000 kPa from the target fuel pressure, there may be a lack of power. If the actual fuel pressure is 40000 kPa higher than the target fuel pressure, P1229 will be stored. When it is lower than the target fuel pressure, a lack of power will occur, but a DTC will not be stored. When the fuel pressure is higher than 200000 kPa, DTC P0088 will be stored.

Target Pump SCV Current	Final pump current target value/ Min.: 0 mA, Max.: 4000 mA	Idling: 923 to 1123 mA	Target value control (pump current)	Suction control valve malfunction Clogged fuel filter element sub-assembly
	Symptoms when out of range: Difficulty starting, lack of power or rough idling
	Diagnostic Note: ECU-calculated value for the suction control valve actuation target current. Value is large when a high fuel pressure is desired. Normally, the value is between 800 and 2500 mA. If the value is stuck at 3000 mA or higher, it indicates that the operation is poor (poor movement due to deposits, etc.). When this deviates from the standard value, it indicates that for some reason, even though the pump is running hard, the actual fuel pressure is inconsistent with the target fuel pressure.

Inj. FB Vol. for Idle
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
Inj. FB Vol. for Idle	Idle stability status integral control volume/ Min.: -80 mm³/st, Max.: 79 mm³/st	-10 to 10 mm³/st	-	-
	Symptoms when out of range: Engine friction problem, compression problem or injector breakdown
	Diagnostic Note: When the actual engine speed does not match the target idling speed, this corrects the injection volume. Abnormal if 10 mm³/st or more, or -10 mm³/st or less. Only calculated and reflected at idle.

Injection Volume
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
Injection Volume	Injection volume/ Min.: 0 mm³/st, Max.: 1279.98 mm³/st	Idling: 3.0 to 10 mm³/st	Calculated value	-
	Symptoms when out of range: -
	Diagnostic Note: Injection amount for each combustion. If injector assemblies are clogged fuel quality is poor, the fuel filter element sub-assembly is clogged, or engine friction increases, "Injection Volume" will increase. If there is a malfunction due to low turbocharger pressure or a low intake air volume, the injection volume is limited and there is a lack of power.

Inj Vol Feedback Learning
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
Inj Vol Feedback Learning	Injection volume feedback learning value: Min.: -10 mm³/st, Max.: 9.92 mm³/st	Idling: -4.0 to 4.0 mm³/st	Learned value	Injector assembly Fuel filter element sub-assembly Inferior quality fuel
	Symptoms when out of range: -
	Diagnostic Note: "Inj Vol Feedback Learning" is calculated by the deviation of injection volume at idle speed when the engine is warmed up. When the engine is warmed up and in a stable idling condition, this learning will be performed. When poor quality fuel or sustained low-speed driving causes a reduction in injector nozzle hole area (reducing injection volume), the "Inj Vol Feedback Learning" will become an abnormal value (for example, 2.0 mm³/st). At that time, if all of "Injection Feedback Value #1 to #4" are within specifications (for example, less than 2 mm³/st), all cylinders are considered to be malfunctioning. If "Injection Feedback Value #1 to #4" is large at only one cylinder (for example, more than 3 mm³/st), that cylinder may have a malfunction. Other than the injector assemblies, fuel filter element sub-assembly pore blockage, poor-quality fuel, compression loss and large engine friction can all cause "Inj Vol Feedback Learning" to be abnormal. When the engine is started cold, the idling speed is high and gradually slows down in accordance with the increase in engine coolant temperature. If the changing value of the idling speed is unstable while the engine is warming up, check "Inj. FB Vol. For Idle". When combustion noise or driveability is bad, check "Inj Vol Feedback Learning" as part of the injection system deterioration diagnosis. Only when the ignition switch is turned off is the learned value updated gradually.

Injection Pressure Correction
Tester Display	Measurement Item/Range	Normal Condition	Type	Cause of Out of Range
Injection Pressure Correction	Injection pressure feedback compensation volume/ Min.: -500 mm³/st, Max.: 780 mm³/st	-400 to 400 mm³/st at standard temperature	Calculated value	Suction control valve malfunction Clogged fuel filter element sub-assembly
	Symptoms when out of range: -
	Diagnostic Note: When the (actual) fuel pressure is equal to the target fuel pressure, this value becomes 0. This indicator can be used for diagnosing supply pump related malfunctions. When this value (absolute value) is large, it indicates that the difference between the actual and target fuel pressure is also large. A positive value indicates that the pressure feed is being increased due to insufficient pressure. A negative value indicates that pressure is being reduced due to excessive rail pressure. When the suction control valve does not close properly, it causes rail overpressure, and this value and the "Pump SCV Learning Value" slip to the negative volume side.

	Symptoms when out of range: Rough idling, black smoke, white smoke, poor driveability, lack of power, abnormal combustion noise, difficult to start
	Diagnostic Note: When idling after warmup, the injection amount for each cylinder is corrected to optimize the difference between the engine speed of each cylinder. Example: For cylinders that are slowing the engine speed compared to other cylinders, the injection volume is increased. "Injection Feedback Val" more than 3.0 mm³/st: Injector breakdown is causing injection volume deviation, or insufficient compression is causing poor combustion. Even if "Injection Feedback Val" for a cylinder is less than -3.0 mm³/st, the cylinder with this value does not necessarily have a problem. Tech Tips The ECM adjusts each cylinder so that the average "Injection Feedback Val" of the 4 cylinders is approximately 0 mm³/st. If more than one cylinder has a positive correction value, a normal cylinder may have a value less than -3.0 mm³/st.

ACTIVE TEST

Tech Tips

Using the intelligent tester to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test.

Perform the Active Test.

Test the Fuel Leak	Pressurize the common rail interior and check for fuel leaks	Stop/Start	Performs inspection of the high pressure fuel system. Engine Speed: 2050 rpm Fuel Pressure: 172000 kPa Target Common Rail Pressure: 176000 kPa Target Pump SCV Current: 1400 mA MAP: 176 kPa mass air flow: 39 g/sec.
Activate the Intank Fuel Pump Relay	Activate the SUB PUMP relay	ON/OFF	Engine is stopped. This test activates the relay for only 60 seconds. After finishing this test, the vehicle does not permit activating the relay again within 60 seconds.
Control the Cylinder#1 Fuel Cut	Stop fuel injection from the No. 1 injector assembly	ON/OFF	Fuel injection is stopped while the test is ON. Confirm that the vehicle is stopped and the engine is idling. If the running condition of the engine does not worsen even though injection of the designated cylinder is stopped, the cylinder can be determined to be malfunctioning.
Control the Cylinder#2 Fuel Cut	Stop fuel injection from the No. 2 injector assembly	ON/OFF	Fuel injection is stopped while the test is ON. Confirm that the vehicle is stopped and the engine is idling. If the running condition of the engine does not worsen even though injection of the designated cylinder is stopped, the cylinder can be determined to be malfunctioning.
Control the Cylinder#3 Fuel Cut	Stop fuel injection from the No. 3 injector assembly	ON/OFF	Fuel injection is stopped while the test is ON. Confirm that the vehicle is stopped and the engine is idling. If the running condition of the engine does not worsen even though injection of the designated cylinder is stopped, the cylinder can be determined to be malfunctioning.
Control the Cylinder#4 Fuel Cut	Stop fuel injection from the No. 4 injector assembly	ON/OFF	Fuel injection is stopped while the test is ON. Confirm that the vehicle is stopped and the engine is idling. If the running condition of the engine does not worsen even though injection of the designated cylinder is stopped, the cylinder can be determined to be malfunctioning.
Check the Cylinder Compression*	Check the cylinder compression pressure	ON/OFF	Fuel injection stops in all cylinders.

Tech Tips

*: When cranking the engine, the Active Test measures the speed of each cylinder. In this Active Test, the fuel of all cylinders is cut when the engine is cranked for approximately 10 seconds.

At this time, the speed of each cylinder is measured. If the speed of one cylinder is more than the other cylinders, it can be determined that the compression pressure of that cylinder is lower than the other cylinders.

Warm up the engine.
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression.

Tech Tips

If the results are not displayed normally, select the display items from the Data List before performing the Active Test. Enter the following menus: Powertrain / Engine and ECT / Data List / Compression / Engine Speed of Cyl #1, Engine Speed of Cyl #2, Engine Speed of Cyl #3, Engine Speed of Cyl #4 and Av Engine Speed of All Cyl.
While the engine is not running, press the RIGHT or LEFT button to change Check the Cylinder Compression to ON.

Tech Tips

After performing the above procedure, the "Check the Cylinder Compression" Active Test will start. Fuel injection for all cylinders is prohibited and the engine speed measurement of each cylinder enters standby mode.
Crank the engine for about 10 seconds.
Monitor the engine speed (Engine Speed of Cyl #1 to #4, Av Engine Speed of All Cyl) displayed on the tester.

Tech Tips

At first, the tester display will show the engine speed measurement of each cylinder to be extremely high. After approximately 10 seconds of engine cranking, the engine speed measurement of each cylinder will change to the actual engine speed.
Note
- After the "Check the Cylinder Compression" Active Test is turned on, it will automatically turn off after 255 seconds.
- When the "Check the Cylinder Compression" test is off and the engine is cranked, the engine will start.
- If the "Check the Cylinder Compression" test needs to be performed after it is turned on and performed once, press "EXIT" to return to the Active Test menu screen. Then perform the "Check the Cylinder Compression" test again.
- Use a fully-charged battery.

SYSTEM CHECK

Activate the Pressure Discharge Valve Check
Tech Tips
- This is the procedure for troubleshooting fuel pressure control malfunctions and combustion problems.
- Malfunctions can be determined by checking the fuel pressure when performing a fuel cut and operating the pressure discharge valve with the intelligent tester.
- During "Pressure Discharge Valve Check", the intelligent tester measures the fuel pressure while the engine is running, after the engine is stopped, and after the pressure discharge valve operates.
1. Connect the intelligent tester to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the tester on.
  Note
  
  Confirm the following conditions:
  
  Engine is idling.
  
  Vehicle is stopped.
  
  Fuel pressure is not extremely high (below 100000 kPa).
  
  Fuel pressure sensor is normal.
  
  Battery voltage is higher than 8 V.
4. Enter the following menus: Powertrain / Engine and ECT / Utility / Pressure Discharge Valve Check.
5. Press "Next".
6. Press "Next" again to proceed.
7. Select the "Pressure Discharge Valve Check" type.
  Tech Tips
  
  "Close to Open Check" opens the pressure discharge valve after the engine stops.
  
  "Always Closed Check" holds the pressure discharge valve closed during the check.
8. Press "Next".
9. Perform troubleshooting based on the measurement results.
  Tech Tips
  
  During "Close to Open Check", if there is no large change in fuel pressure when the pressure discharge valve is closed while the engine is running and after the engine is stopped, and if the value is 0 kPa when the pressure discharge valve is open, the system is normal.
  
  Perform "Always Closed Check" if the value is not 0 kPa when the pressure discharge valve is open during "Close to Open Check". If the results are the same as during "Close to Open Check", there is a pressure discharge valve operation malfunction.
  
  If the fuel temperature is high, perform "Pressure Discharge Valve Check" after the fuel has cooled to the outside air temperature.
  
  If a large amount of fuel is leaking, the fuel pressure decreases when the engine is stopped. However, the condition of the pressure discharge valve can still be determined by comparing the measurement results of "Close to Open Check" and "Always Closed Check".
