Manual Shifting Test: Initialization

  1. RESET MEMORY 
    CAUTION: Perform the RESET MEMORY (AT initialization) when replacing the automatic transaxle assy, engine assy or ECM.
    NOTE: Hand-held tester only

    HINT:

    The ECM memorizes the condition that the ECT controls the automatic transaxle assy and engine assy according to those characteristics. Therefore, when the automatic transaxle assy, engine assy, 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. Turn the ignition switch off:
    2. Connect the hand-held tester to the DLC3.
    3. Turn the ignition switch to the ON position and turn the hand-held tester main switch on.
    4. Select the item "DIAGNOSIS/ENHANCED OBD II".
    5. Perform the reset memory procedure from the ENGINE menu.
    CAUTION: After performing the RESET MEMORY, be sure to perform the ROAD TEST  described earlier.

    HINT:

    The ECM learns through use of the ROAD TEST.
