AUTOMATIC TRANSMISSION SYSTEM(for 1UR-FE) INITIALIZATION


  1. RESET MEMORY

    Note


    • Perform Reset Memory (AT initialization) when replacing the automatic transmission assembly, 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 control conditions of the automatic transmission assembly and engine assembly. Therefore, when the automatic transmission assembly, 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 engine switch on (IG).

    3. Turn the GTS on.

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

      Note

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

      Tech Tips

      The ECM learns through the Road Test.
