AUTOMATIC TRANSMISSION SYSTEM(for 1GD-FTV) INITIALIZATION


  1. RESET MEMORY

    Note


    • Perform Reset Memory (AT initialization) when replacing the automatic transmission assembly, transmission valve body assembly or any of the shift solenoid valves.

    • Reset Memory can be performed only with the GTS.

    Tech Tips

    The ECM memorizes the vehicle conditions when the ECT controls the automatic transmission assembly and transmission valve body assembly. Therefore, when the automatic transmission assembly, transmission valve body assembly or any of the shift solenoid valves has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.

    The reset procedure is as follows.


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.


      Powertrain > Engine > Utility
      Tester Display
      Reset Memory

      Note

      After performing Reset Memory, be sure to perform the Road Test described earlier.

      Tech Tips

      The ECM learns through the Road Test.

  2. ATF THERMAL DEGRADATION ESTIMATE RESET

    Note

    If either of the following conditions is met, perform ATF Thermal Degradation Estimate Reset.


    • The ATF has been replaced.

    • Approximately 50% or more of the ATF has been replaced during a repair of the transmission or a similar operation.


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

      Note

      Do not start the engine.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Utility / ATF Thermal Degradation Estimate Reset.
