AUTOMATIC TRANSMISSION SYSTEM INITIALIZATION


  1. RESET MEMORY

    Note


    • Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assembly, valve body, engine assembly or TCM.

    • The RESET MEMORY can be performed only with the GTS.

    Tech Tips

    The TCM memorizes the condition that the ECT controls the automatic transmission assembly and engine assembly according to those characteristics. Therefore, when the automatic transmission assembly, valve body, transmission wire, engine assembly, or TCM has been replaced, it is necessary to reset the memory so that the TCM can memorize the new information.

    Reset procedure is as follows.


    1. Turn the ignition switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch ON.

    4. Turn the GTS main switch on.

    5. Enter the following menu: Powertrain / ECT / Utility / Reset Memory. Then, press "Next".

    6. Perform the reset memory procedure from the main menu.

      CAUTION:

      After performing the RESET MEMORY, be sure to perform the ROAD TEST Click here described earlier.

      Tech Tips

      The TCM is learned by performing the ROAD TEST.
