DATA LIST
Using the GTS 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.
In the following table, 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.
When reading values of the Data List, confirm that PM regeneration is not activated (value of "After Injection Period" is 0) by entering the following menus: Powertrain / Engine and ECT / Data List / After Injection Period.
If PM regeneration is activated (value of "After Injection Period" is not 0), drive the vehicle until PM regeneration is complete (value of "After Injection Period" becomes 0).
When idling, EGR cut occurs under either of the following conditions:
PM regeneration is activated.
Idling time is long (approximately 20 minutes or more).
If EGR is cut off when idling and PM regeneration is not activated, when the vehicle is driven in 4th gear between 90 and 100 km/h (56 and 62 mph) for 30 minutes, EGR resumes.
Warm up the engine.
Turn the ignition switch off.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Start the engine.
Turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Data List.
To display the list box, press the pull down menu button next to Primary. Then select a measurement group.
When you select a measurement group, the ECU data belonging to that group is displayed.

The speed of each cylinder can be measured (compression test) by using the GTS.
In the compression test, perform Active Test using GTS (Check the Cylinder Compression) and crank the engine for approximately 10 seconds. At this time, the speed of each cylinder is measured. If the speed of one cylinder is higher than the other cylinders, the compression pressure of that cylinder is determined to be lower than the other cylinders.
Warm up the engine.
Turn the ignition switch off.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression / Data List / 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.
Push the snapshot button to turn the snapshot function on.
Using the snapshot function, data can be recorded during the Active Test.
While the engine is not running, press the RIGHT or LEFT button to Change the Cylinder Compression to ON.
After performing the above procedure, Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited and each cylinder engine speed measurement 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 .
After approximately 10 seconds of engine cranking, the engine speed measurement of each cylinder will change to the actual engine speed.
Do not crank the engine continuously for 20 seconds or more.
If Check the Cylinder Compression needs to be performed after it is turned ON and performed once, press Exit to return to the Active Test menu screen. Then perform Check the Cylinder Compression again.
Use a fully-charged battery.
Stop cranking the engine, and then change Check the Cylinder Compression to OFF after the engine stops.
If the Active Test is changed to OFF while the engine is being cranked, the engine will start.
Push the snapshot button to turn the snapshot function off.
Select the recorded data and display the data as a graph.
Check the change in engine speed values.
For reference, the results of a "real-vehicle check" are as shown below:
Engine Speed of Cyl #1: 321 rpm
Engine Speed of Cyl #2: 317 rpm
Engine Speed of Cyl #3: 320 rpm
Engine Speed of Cyl #4: 317 rpm

ACTIVE TEST
Do not perform the Active Test while stop and start control is being performed. (w/ stop and start system)
Using the GTS 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 GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Active Test.
Perform the Active Test.

Check the Cylinder Compression | Check the cylinder compression pressure | ON/OFF | Fuel injection stops in all cylinders* |
*: 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 higher than the other cylinders, the compression pressure of that cylinder is determined to be lower than the other cylinders.
Warm up the engine.
Turn the ignition switch off.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression.
To display the entire Data List, press the pull down menu button next to Primary. Then select Compression.
Push the snapshot button to turn the snapshot function on.
Using the snapshot function, data can be recorded during the Active Test.
While the engine is not running, press the ON button to change Check the Cylinder Compression to on.
After performing the above procedure, Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited and each cylinder engine speed measurement enters standby mode.
Crank the engine for about 10 seconds.
Monitor the engine speed (Engine Speed of Cyl #1 to #4) displayed on the GTS.
After approximately 10 seconds of engine cranking, the engine speed measurement of each cylinder will change to the actual engine speed.
Do not crank the engine continuously for 20 seconds or more.
If it is necessary to crank the engine again after Check the Cylinder Compression has been changed to ON and the engine has been cranked once, press Exit to return to the Active Test menu screen. Then change Check the Cylinder Compression to ON and crank the engine.
Use a fully-charged battery.
Stop cranking the engine, and then change "Check the Cylinder Compression" to OFF after the engine stops.
If the Active Test is changed to OFF while the engine is being cranked, the engine will start.
Push the snapshot button to turn the snapshot function off.
Select "Stored Data" on the GTS screen, select the recorded data and display the data as a graph.
If the data is not displayed as a graph, the change of the values cannot be observed.
Check the change in engine speed values.
SYSTEM CHECK
Activate the Pressure Discharge Valve Check
This procedure is for troubleshooting fuel pressure control malfunctions and combustion problems.
Malfunctions can be determined by checking the fuel pressure when performing fuel cut and operating the pressure control valve with the GTS.
During "Pressure Discharge Valve Check", the GTS measures the fuel pressure while the engine is running, after the engine is stopped, and after the pressure control valve operates.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Confirm the following conditions:
Engine is idling.
Vehicle is stopped.
Fuel pressure is not extremely high (less than 100000 kPa).
Fuel pressure sensor is normal.
Battery voltage is higher than 8 V.
Enter the following menus: Powertrain / Engine and ECT / Utility / Pressure Discharge Valve Check.
Powertrain > Engine and ECT > UtilityTester Display |
---|
Pressure Discharge Valve Check |
Press "Next".
Press "Next" again to proceed.
Select the check type "Valve Check for Graph".
Press "Next" again to proceed.
Press "Start" again to proceed.
*1 | Engine Speed | *2 | Fuel Pressure |
*3 | Pressure Discharge Valve | - | - |
*4: When "Start" is pressed, the pressure discharge valve check begins.
*5: If "Save" is pressed after the pressure discharge valve check, the data recorded during the valve check can be saved.
Select the check type "Close to Open Check" or "Always Closed Check".
"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.
Press "Next".
Perform troubleshooting based on the measurement results.
During "Close to Open Check", if there is no large change in fuel pressure when the pressure control valve is closed while the engine is running and after the engine is stopped, and if the value is approximately 0 kPa when the pressure control valve is open, the system is normal.
Perform "Always Closed Check" if the value is not 0 kPa when the pressure control valve is open during "Close to Open Check". If the results are the same as during "Close to Open Check", there is a pressure control valve operation malfunction.
If the fuel temperature is high, wait until the fuel temperature becomes the same as the ambient temperature before performing "Pressure Discharge Valve Check".
If a large amount of fuel is leaking, the fuel pressure decreases when the engine is stopped. However, the condition of the pressure control valve can still be determined by comparing the measurement results of "Close to Open Check" and "Always Closed Check".
Engine Oil Pressure Control Check
Check whether the oil pressure control system is operating properly when the oil pressure switching valve is forcibly operated.
Perform this check when DTC P0524 is output.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Start the engine and warm it up.
Confirm that the engine coolant temperature is between 70 and 90°C (158 and 194°F) after the engine is warmed up, as the oil pressure changes according to the engine coolant temperature.
Enter the following menus: Powertrain / Engine and ECT / Utility / Engine Oil Pressure Control Check.
Powertrain > Engine and ECT > UtilityTester Display |

Engine Oil Pressure Control Check |
Confirm the following conditions:
Engine is idling.
Vehicle is stopped.
Shift lever is in neutral.
Engine coolant temperature is in specified range.
Press "Next".
Even when the engine is warmed up, there are some instances where the oil pressure control system check cannot be performed.
The engine speed will increase during the oil pressure control system check.
Perform troubleshooting based on the measurement results.
The average oil pressure over 1 second when the valve is operated is displayed.
The engine oil pressure measured every 0.1 seconds is displayed on the detailed information screen.
