AUTOMATIC TRANSAXLE SYSTEM INITIALIZATION


  1. RESET TRANSAXLE COMPENSATION CODE

    Note


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


      • Transmission valve body assembly

      • Solenoid (SL3) valve

      • Solenoid (SL4) valve

      • ECM

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

    Tech Tips

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

    Therefore, if the automatic transaxle assembly, transmission valve body assembly, solenoid (SL3 and SL4) valves or ECM 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. Make sure the shift lever is in P or N.

    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 / Transmission / Utility / A/T Code Reset.


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

    6. Press "Next" again to proceed.

      Note

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

    7. 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, if the automatic transaxle assembly, transmission valve body assembly, solenoid (SL3 and SL4) valves or ECM 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 / Transmission / Utility / Reset Memory.


      Powertrain > Transmission > Utility
      Tester Display
      Reset Memory

    5. Press "Next".

      Note

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

  3. PERFORM ROAD TEST TO ALLOW ECM 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 / Engine / Data List / Throttle Sensor Position.


      Powertrain > Engine > Data List
      Tester Display
      Throttle Sensor Position

    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 Sensor Position": 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 Sensor Position": 25% to 35%

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

  4. BLEED AIR FROM OIL PUMP WITH MOTOR ASSEMBLY

    Note

    Bleed the oil pump with motor assembly (automatic transaxle assembly) after replacing the automatic transaxle assembly or automatic transaxle fluid.


    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 / Stop and Start / Utility / Oil Pump Air Bleeding.


      Powertrain > Stop and Start > Utility
      Tester Display
      Oil Pump Air Bleeding
