  1. RESET TRANSAXLE COMPENSATION CODE

    Note


    • If the following parts have been replaced, initialize the ECM and perform the following Reset Memory and Perform Road Test to Allow ECM to learn steps.

      - Valve body assembly

      - Shift solenoid valve SL3

      - Shift solenoid valve SL4

      - ECM

    • The transaxle compensation code can only be initialized with the GTS.

    Tech Tips

    The ECM memorizes the vehicle conditions when the ECT controls the automatic transaxle assembly. Therefore, when the automatic transaxle assembly or ECM has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information. Reset procedure is as follows:


    1. Move the shift lever to N or P.

    2. Turn the ignition switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Engine and ECT / Utility / A/T Code Reset.


      Powertrain > Engine and ECT > Utility
      Tester Display
      A/T Code Reset

    7. Press "Next" to proceed.

      Note

      After the transaxle compensation code is initialized, perform the following Reset Memory and Perform Road Test to Allow ECM to learn steps.

    8. Press "Exit".

  2. RESET MEMORY

    Note

    Reset Memory can be performed only with the GTS.

    Tech Tips

    The ECM (ECT) memorizes the vehicle conditions when controlling the automatic transaxle assembly and engine assembly.

    Therefore, when the automatic transaxle assembly, valve body assembly, shift solenoid valve SL3, shift solenoid valve SL4, or ECM has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.


    1. Reset procedure is as follows.


      1. Turn the ignition switch off.

      2. Connect the GTS to the DLC3.

      3. Turn the ignition switch to ON.

      4. Turn the GTS on.

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


        Powertrain > Engine and ECT > Utility
        Tester Display
        Reset Memory

      6. Press "Next".

        Note

        After performing Reset Memory, be sure to perform Perform Road Test to Allow ECM to Learn described below.

  3. PERFORM ROAD TEST TO ALLOW ECM TO LEARN

    Note

    Perform the following procedure while strictly observing all traffic laws and speed limits.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the GTS to the DLC3.

    4. Start the engine.

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Engine and ECT / Data List / Throttle Sensor Position.


      Powertrain > Engine and ECT > Data List
      Tester Display
      Throttle Sensor Position

    7. With the shift lever in P and the vehicle at a standstill, confirm the accelerator pedal depression amount when the "Throttle Sensor Position" value in the Data List becomes 15%.

    8. From a standstill, accelerate the vehicle to the highest possible speed with the "Throttle Sensor Position" value at 15% or less while keeping the accelerator pedal position fixed.

    9. If shift shock is large, repeat the previous step until shift shock no longer occurs.

    10. With the vehicle at a standstill, confirm the accelerator pedal depression amount when the "Throttle Sensor Position" value in the Data List becomes 25 to 35%.

    11. From a standstill, accelerate the vehicle to the highest possible speed with the "Throttle Sensor Position" value at 25 to 35% while keeping the accelerator pedal position fixed.

    12. If shift shock is large, repeat the previous step until shift shock no longer occurs.
