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 singles 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 for reference only. Do not depend solely on these values when determining whether or not a part is faulty.
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 / Data List.
Check the values by referring to the table below.
Tech Tips
If no idling conditions are specified, make sure the shift lever is in neutral, and the air conditioning switch and all accessory switches are off.

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.
Warm up the engine.
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test.
According to the display on tester, perform the Active Test.
| Tester Display | Test Part | Control Range | Diagnostic Note |
|---|---|---|---|
| Control the Injection Volume | Change injection volume | Between -12.5 and 24.8% |
|
| Control the Injection Volume for A/F Sensor | Change injection volume | Lower by 12.5% or increase by 24.8% |

Tech Tips
*: When performing the Active Test item "Check the Cylinder Compression" and then cranking the engine, the ECM stops the fuel injection and ignition, and measures the engine speed for each cylinder. If the speed of one cylinder is higher than the others, the compression pressure of that cylinder can be concluded to be less than the others.
Warm up the engine.
Turn the ignition switch off.
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 / Check the Cylinder Compression.
Select the following monitor items: Compression / Engine Speed of Cyl #1 to Engine Speed of Cyl #4, Av Engine Speed of All Cyl.
Press the RIGHT or LEFT button to change Check the Cylinder Compression to ON.
Tech Tips
Fuel injection and ignition for all the cylinders are prohibited at this time, and the engine speed measurement of each cylinder will enter standby mode.
Crank the engine until the monitor item values "Engine speed of Cyl #1 to Engine Speed of Cyl #4" and "Av Engine Speed of All Cyl" change.
Monitor the engine speed (Engine Speed of Cyl #1 to Engine Speed of Cyl #4, Av Engine Speed of All Cyl) displayed on the intelligent tester.
Tech Tips
The intelligent tester displays extremely high values before cranking the engine. The engine speed of each cylinder is measured while cranking the engine and then the intelligent tester displays the actual engine speed values.
Note
The Active Test item "Check the Cylinder Compression" will automatically turn off 255 seconds after the Active Test is turned on.
When the "Check the Cylinder Compression" is OFF and the engine is cranked, the engine will start.
If the "Check the Cylinder Compression" test needs to be performed again after the engine speed measurement of each cylinder has been 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.
