Monitor Drive Pattern
MONITOR DRIVE PATTERN FOR ECT TESTa. Perform this drive pattern as one method to simulate the detection conditions of the ECT malfunctions. (The DTCs may not be detected due the actual driving conditions. And some codes may not be detected through this drive pattern).
HINT:
Preparation for driving
- Warm up the engine sufficiently. (Engine coolant temperature is 60 °C (140 °F) or higher)
- Drive the vehicle when the atmospheric temperature is -10 °C (14 °F) or higher. (Malfunction is not detected when the atmospheric temperature is -10 °C (14 °F) or less)
Driving note
- Drive the vehicle through all gears.
Stop -> 1st -> 2nd -> 3rd -> 4th -> 5th -> 5th (lock-up ON).
- Perform engine brake test in the S position.
While driving in the 5(S) position and 6th gear lock-up, shift into the "-" position and down-shift from 5th to 4th, 4th to 3rd, 3rd to 2nd, 2nd to 1st.
Check that the engine brake performs properly whenever down-shift takes place.
- Repeat the above driving pattern three times or more.
NOTE:
- The monitor status can be checked using the OBD II scan tool. When using the hand-held tester, monitor status can be found in the "ENHANCED OBD II/DATA LIST" or under "CARB OBD II".
- In the event that the drive pattern must be interrupted (possibly due to traffic conditions or other factors) the drive pattern can be resumed and, in most cases, the monitor can be completed.
CAUTION: Perform this drive pattern on a level road as much as possible and strictly observe the posted speed limits and traffic laws while driving.
NOTE: It is necessary to drive the vehicle for approximately 30 minutes to detect DTC P0711 (ATF temperature sensor malfunction).
