AUTOMATIC TRANSAXLE SYSTEM MONITOR DRIVE PATTERN


  1. TEST MONITOR DRIVE PATTERN FOR ECT

    CAUTION:

    Perform the following procedure on a level surface while strictly observing all traffic laws and speed limits.

    Tech Tips

    Performing this drive pattern is one method to simulate the ECM (ECT) malfunction detection conditions.

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


    1. Preparation for driving


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

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

        Some malfunctions are not detected when the ambient temperature is less than -10°C (14°F).

    2. Drive pattern

      B007XQNE69

      *: Drive at a speed in the highest gear that will cause lock-up to engage. The vehicle can be driven at a speed lower than the speed shown in the above diagram under lock-up.


      1. Drive the vehicle through all of the gears.

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

      2. Confirm engine braking using the M position. While driving with M6 range selected and 6th gear lock-up on, move the shift lever toward "-" and downshift from 6th to 5th, 5th to 4th, 4th to 3rd, 3rd to 2nd, 2nd to 1st.

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

        Note


        • When using the GTS, the monitor status can be checked in the Data List.

        • 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.

        • It is necessary to drive the vehicle for approximately 30 minutes to detect DTC P071000 (ATF temperature sensor malfunction).
