WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
  1. 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.

    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.

    1. Warm up the engine.
    2. Turn the ignition switch off.
    3. Connect Techstream to the DLC3.
    4. Turn the ignition switch on (IG).
    5. Turn on the tester.
    6. Enter the following items: "Powertrain / ECT / Data List".
    7. According to the display on the tester, read "Data List".
