Monitor Drive Pattern

HINT: 

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

Some 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.

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

2. Drive pattern
   1. Drive the vehicle through all the gears.

      Stop → 1st → 2nd → 3rd → 4th → 5th → 6th → 6th (lock-up ON) → 7th → 7th (lock-up ON) → 8th → 8th (lock-up ON).

   2. Perform an engine braking test with the shift lever in D. While driving in the D8 range and 8th gear lock-up, operate the "-" paddle switch and down-shift from 8th → 7th, 7th → 6th, 6th → 5th, 5th → 4th, 4th → 3rd, 3rd → 2nd and 2nd → 1st.

      Check that engine braking is normal for every down-shift.

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

      • When using the Techstream, the monitor status can be checked in the Data List. Refer to DATA LIST / ACTIVE TEST .
      • 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.

HINT: 

*: Drive at a speed in top 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 the lock-up condition.
