AUTOMATIC TRANSAXLE SYSTEM MONITOR DRIVE PATTERN


  1. TEST MONITOR DRIVE PATTERN FOR ECT

    CAUTION:

    Perform this drive pattern on a level surface and strictly observe the posted speed limits and traffic laws while driving.

    Tech Tips

    Performing this drive pattern is one method to simulate the malfunction detection conditions of the ECT.

    The DTCs may not be detected through ordinary, everyday driving. Also, DTCs may not be detected through this drive pattern.


    1. Preparation for driving


      1. Warm up the engine sufficiently (engine coolant temperature is 60°C (140°F) or higher).

      2. Drive the vehicle when the atmospheric temperature is -10°C (14°F) or higher.

        Malfunctions are not detected when the atmospheric temperature is below -10°C (14°F).

    2. Drive pattern


      1. Drive the vehicle through all the gears.

        Stop → 1st → 2nd → 2nd (lock-up on) → 3rd → 3rd (lock-up on) → 4th → 4th (lock-up on) → 5th → 5th (lock-up on) → 6th → 6th (lock-up on).

      2. Perform the engine brake test with the shift lever in D. While driving in 6th gear lock-up, operate the "-" shift paddle switch and down-shift from 6th → 5th, 5th → 4th, 4th → 3rd, 3rd → 2nd and 2nd → 1st.

        Check that the engine brake operates properly when each down-shift takes place.

      3. Repeat the above drive pattern 3 times or more.

        Note


        • When using the intelligent tester, the monitor status can be checked in the Data List Click here.

        • In the event that the drive pattern must be interrupted (due to traffic conditions or other factors), the drive pattern can be resumed and, in most cases, the monitor can be completed.

    Tech Tips

    *: Drive at such a speed in the uppermost gear so as to engage lock-up. The vehicle can be driven at a speed lower than the speed shown in the above diagram in lock-up.

    Note

    It is necessary to drive the vehicle for approximately 30 minutes to detect DTC P0711 (transmission fluid temperature sensor "A" performance).
