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 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 engine switch off.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG) and turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / Data List.

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.
Data List can be displayed during Active Test.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG) and turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test.
According to the display on the 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% |
|
| Activate the VSV for Evap Control | Activate purge VSV control | ON/OFF | - |
| Control the Fuel Pump/Speed | Activate fuel pump (C/OPN Relay) | ON/OFF | The test is possible when the engine is stopped. |
| Connect the TC and TE1 | Turn on and off TC and TE1 connection | ON/OFF |
|
| Control the Idle Fuel Cut Prohibit | Prohibit idling fuel cut control | ON/OFF | - |
| Control the Electric Cooling Fan | Control electric cooling fan | ON/OFF | - |
| Control the ETCS Open/Close Slow Speed | Throttle actuator | Close/Open | The test is possible when the following conditions are met:
|
| Control the ETCS Open/Close Fast Speed | Throttle actuator | Close/Open | |
| Control the Cylinder #1 Fuel Cut | Cylinder #1 injector fuel cut | ON/OFF | The test is possible while the vehicle is stopped and the engine is idling. |
| Control the Cylinder #2 Fuel Cut | Cylinder #2 injector fuel cut | ON/OFF | |
| Control the Cylinder #3 Fuel Cut | Cylinder #3 injector fuel cut | ON/OFF | |
| Control the Cylinder #4 Fuel Cut | Cylinder #4 injector fuel cut | ON/OFF | |
| Control the All Cylinder Fuel Cut | All cylinder injector fuel cut | ON/OFF | |
| Check the Cylinder Compression* | Check the cylinder compression pressure (measuring engine speed for each cylinder) |
ON/OFF | Fuel injection and ignition is stopped in all the 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, and cranking occurs 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.
