LANE DEPARTURE ALERT SYSTEM DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    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. Connect the Techstream to the DLC3.

    2. Turn the engine switch on (IG).

  2. ACTIVE TEST

    Tech Tips

    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: Chassis / Lane Departure Alert / Active Test.

    5. Perform Active Test according to the display on Techstream.

      Tech Tips

      The engine switch must be turned on to proceed with the Active Test using the Techstream.

      Lane Departure Alert
      Tester Display Test Part Control Range Diagnostic Note
      LDA Buzzer Combination meter assembly OFF or ON Vehicle condition: Vehicle stopped

    6. Enter the following menus: Body Electrical / Combination Meter / Active Test.

    7. Perform Active Test according to the display on Techstream.

      Tech Tips

      The engine switch must be turned on to proceed with the Active Test using the Techstream.
