Data List / Active Test

WARNING: This page is about a different car, the 2008 Toyota Yaris. However, it is still accessible from the selected car via links, so may be relevant.
  1. READ DATA LIST 

    HINT:

    Using a 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 early in troubleshooting is one way to save diagnostic time.

    1. Warm up the engine.
    2. Turn the ignition switch to OFF.
    3. Connect a Techstream to the DLC3.
    4. Turn the ignition switch to ON.
    5. Turn the tester on.
    6. Enter the following menus: Body Electrical / Air Conditioner / Data List /
    7. According to the display on tester, read the "Data List".

  2. PERFORM ACTIVE TEST 

    HINT:

    Using a Techstream to perform the 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.

    1. Connect a Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the tester on.
    4. Enter the following menus: Body Electrical / Air Conditioner / Active Test /
    5. According to the display on tester, perform the "Active Test".
