AUTOMATIC HIGH BEAM SYSTEM DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    Using the GTS 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. Turn the engine switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the engine switch on (IG).

    4. Turn the GTS on.

    5. Enter the following menus: Body Electrical / Main Body / Data List.

    6. Read the Data List according to the display on the GTS.

      Tech Tips

      *: The details of each value of the Control Range are as follows:

      Range Condition Control Condition Diagnostic Note
      Undetec Automatic high beam sensor being initialized Control suspended (low beam headlights illuminated) -
      CAM NA Automatic high beam sensor temporarily disabled due to high temperature, unclear image (due to dirt, fog, etc.), etc. Control suspended (low beam headlights illuminated) -
      No sens No lights detected High beam headlights illuminated Only when vehicle speed within operation speed range

  2. ACTIVE TEST

    Tech Tips

    Using the GTS 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. Turn the engine switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the engine switch on (IG).

    4. Turn the GTS on.

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

    6. Perform the Active Test according to the display on the GTS.
