Data List / Active Test [03/2019 - 09/2020]

  1. 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 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 A/C switch off.
    3. Turn the engine switch off.
    4. Connect the Techstream to the DLC3.
    5. Turn the engine switch on (IG).
    6. Turn the Techstream on.
    7. Enter the following menus: Powertrain / Engine / Data List.
    8. According to the display on the Techstream, read the Data List.

      HINT: 

      Normal Condition: If no idling conditions are specified, the shift lever should be in N (Neutral) or P, and the A/C switch and all accessory switches should be off.

  2. 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.

    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine / Active Test.
    5. According to the display on the Techstream, perform the Active Test.

      Powertrain > Engine > Active Test 

      Tester Display Measurement Item Control Range Diagnostic Note
      Control the Voltage of Alternator Requested output voltage of generator regulator during forced activation Between 12.5 and 14.7 V Test is possible after engine start
