ENGINE IMMOBILISER SYSTEM(w/o Power Switch) 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.

    • If the ignition switch cannot be turned to ON, communication with the GTS can be performed by connecting the GTS to the vehicle and turning a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and vehicle begins.

    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 ignition switch to ON.

    3. Turn the GTS on.

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

    5. Enter the following menus: Powertrain / Hybrid control / Data List.

    6. According to the display on the GTS, read the Data List.

      Problems may be caused by the following:


      • A key from a different vehicle is being used.

      • Malfunctions in the key, transponder key ECU assembly or transponder key amplifier.
      Different Encrypt Code*1 Code status between transponder chip and transponder key ECU assembly / OK or NG

      OK: Codes of transponder chip and transponder key ECU assembly match

      NG: Codes of transponder chip and transponder key ECU assembly do not match

      Problems may be caused by the following:


      • A key from a different vehicle is being used.

      • Malfunctions in the key, transponder key ECU assembly or transponder key amplifier.
      Abnormal Status*1 Transponder chip status signal / OK or NG

      OK: Transponder chip status signal normal

      NG: Transponder chip status signal malfunction (malfunction in code computation in key/transponder key ECU assembly)

      Problems may be caused by the following:


      • Communication errors due to external electric wave noise (LF).

      • Malfunctions in the key, transponder key ECU assembly or transponder key amplifier.
      Bcc Malfunction*1 Bcc signal status of transponder chip / OK or NG

      OK: Bcc signal normal
