    Note


    • Perform the RESET MEMORY (AT initialization) when replacing the automatic transaxle assembly, engine assembly or ECM.

    • The RESET MEMORY can be performed only with Intelligent tester.

    Tech Tips

    The ECM memorizes the condition that the ECT controls the automatic transaxle assembly and engine assembly according to those characteristics. Therefore, when the automatic transaxle assembly, engine 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. Turn the ignition switch off.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the ignition switch on (IG) and push the intelligent tester main switch on.

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

    5. 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 ECM is learned by performing the ROAD TEST.

  4. OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (When Using Intelligent Tester) (Vehicle Stability Control System)

    Note


    • While obtaining the zero points, keep the vehicle stationary and do not vibrate, tilt, move, or shake it. (Do not start the engine.)

    • Be sure to perform this procedure on a level surface (with an inclination of less than 1 degree).


    1. Clear the zero point calibration data.


      1. Turn the ignition switch off.

      2. Check that the steering wheel is in the straight-ahead position.

      3. Check that the shift lever is in the P position.
