GRILLE SHUTTER SYSTEM DATA LIST / ACTIVE TEST


  1. 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.

    DATA LIST

    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 GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Grille Shutter / Data List.

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

  2. 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.

    ACTIVE TEST


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Grille Shutter / Active Test.

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


      Body Electrical > Grill Shutter > Active Test
      Tester Display Measurement Item Control Range Diagnostic Note
      Shutter Closing Operation Lock Detection Grille shutter OFF or Close Closing operation performed until motor stops due to lock detection.
      Shutter Opening Operation Lock Detection Grille shutter OFF or Open Opening operation performed until motor stops due to lock detection.
      Shutter Closing Operation Fixed Length Grille shutter OFF or Close Closing operation performed until motor stops due to reaching a certain operation amount or lock detection.
      Shutter Opening Operation Fixed Length Grille shutter OFF or Open Opening operation performed until motor stops due to reaching a certain operation amount or lock detection.
