Data List / Active Test

DATA LIST

HINT:

Using the Techstream 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 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 Techstream to the DLC3.
Turn the ignition switch to ON.
Turn the Techstream on.
Enter the following menus: Powertrain / Engine and ECT / Data List.
According to the display on the Techstream, read the Data List.

ACTIVE TEST

HINT:

Using the Techstream 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 Techstream to the DLC3.
Turn the ignition switch to ON.
Turn the Techstream on.
Enter the following menus: Powertrain / Engine and ECT / Active Test.
According to the display on the Techstream, perform the Active Test.

Fuel injection and ignition for all cylinders are prohibited at this time, and each cylinder's engine speed measurement will enter standby mode.
Crank the engine until the monitor item values "Engine speed of Cyl #1 to #4" and "Av Engine Speed of All Cyl" change.
Monitor the engine speed (Engine Speed of Cyl #1 to #4, Av Engine Speed of All Cyl) displayed on the Techstream.
HINT:

The Techstream displays the values to be extremely high before cranking the engine. Each cylinder's engine speed is measured while cranking the engine and then the Techstream 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 speed measurements have 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.
