Data List / Active Test [11/2021 - 12/2023]

  1. DATA LIST 

    HINT: 

    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. Enter the following menus:
      1. Body Electrical / Main Body / Data List.
      2. for Stereo Camera Type:

        Body Electrical / AFS / Data List.

      3. for Stereo Camera Type:

        Body Electrical / AFS (Sub) / Data List.

      4. for Mono Camera Type:

        Body Electrical / HL AutoLeveling / Data List.

      5. for Mono Camera Type:

        Body Electrical / HL AutoLeveling (Sub) / Data List.

      6. Chassis / Steering Angle Sensor / Data List.
      7. Body Electrical / Combination Meter / Data List.
      8. Body Electrical / Front Recognition Camera (Front Lighting Control) / Data List.
      9. Chassis / Front Recognition Camera / Data List.
      10. Body Electrical / Power Integration No. 3 / Data List.
    2. Read the Data List according to the display on the GTS.
