AUTOMATIC TRANSAXLE SYSTEM INITIALIZATION


  1. RESET TRANSAXLE COMPENSATION CODE

    Note


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


      • Transmission valve body assembly

      • Shift solenoid valve SL3

      • Shift solenoid valve SL4

      • TCM

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

    Tech Tips

    The TCM (ECT) memorizes the vehicle conditions when controlling the automatic transaxle assembly and engine assembly. Therefore, if the automatic transaxle assembly, transmission valve body assembly, shift solenoid valve SL3, shift solenoid valve SL4 or TCM has been replaced, it is necessary to reset the memory so that the TCM can memorize the new information. The reset procedure is as follows:


    1. Move the shift lever to N or P.

    2. Turn the engine switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the GTS on.

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


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

    7. Press "Next" again to proceed.

      Note

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

    8. Press "Exit".

  2. RESET MEMORY

    Note

    Reset Memory can be performed only with the GTS.

    Tech Tips

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

    Therefore, if the automatic transaxle assembly, transmission valve body assembly, shift solenoid valve SL3, shift solenoid valve SL4, or TCM has been replaced, it is necessary to reset the memory so that the TCM can memorize the new information. The reset procedure is as follows:


    1. Turn the engine switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the engine switch on (IG).

    4. Turn the GTS on.

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


      Powertrain > ECT > Utility
      Tester Display
      Reset Memory

    6. Press "Next".

      Note

      After performing Reset Memory, be sure to perform Perform Road Test to Allow TCM to Learn.

  3. PERFORM ROAD TEST TO ALLOW TCM TO LEARN

    CAUTION:

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


    1. Warm up the engine.

    2. Turn the engine switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / ECT / Data List / Throttle Position from EFI.


      Powertrain > ECT > Data List
      Tester Display
      Throttle Position from EFI

    7. From a standstill, achieve highest possible speed with the accelerator pedal opened 15% or less. Keep the accelerator pedal opening angle steady while driving the vehicle.

      Tech Tips

      "Throttle Position from EFI": 15% or less

    8. Repeat the previous step until shift shock no longer occurs.

    9. From a standstill, achieve highest possible speed with the accelerator pedal opened 25% to 35%. Keep the accelerator pedal opening angle steady while driving the vehicle.

      Tech Tips

      "Throttle Position from EFI": 25% to 35%

    10. Repeat the previous step until shift shock no longer occurs.
