Automatic Transaxle System -- Data List / Active Test



DATA LIST
HINT:
Using 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.
NOTICE:
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.

  1. Warm up the engine.

  2. Turn the ignition switch off.

  3. Connect Techstream to the DLC3.

  4. Turn the ignition switch to the ON position.

  5. Turn on the tester.

  6. Select the item "Powertrain / Engine and ECT / Data List".

  7. According to the display on the tester, read the "Data List".

ACTIVE TEST
HINT:
Using Techstream to perform Active Test 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 Test early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Test.

  1. Warm up the engine.

  2. Turn the ignition switch off.

  3. Connect Techstream to the DLC3.

  4. Turn the ignition switch to the ON position.

  5. Push the "ON" button of Techstream.

  6. Select the item "Powertrain / Engine and ECT / Active Test".

  7. According to the display on tester, perform the "Active Test".
