Monitor Drive Pattern

TEST MONITOR DRIVE PATTERN FOR ECT
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.

HINT:
- Perform this drive pattern as one method to simulate the ECT's malfunction detection conditions.
- 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 less than -10°C (14°F).
2. Drive pattern
  1. Drive the vehicle through all the gears.
    Stop --> 1st --> 2nd --> 3rd --> 4th --> 5th --> 5th (lock-up ON).
  2. Repeat the above driving pattern 3 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 by enter the following menus: ENHANCED OBD II/DATA LIST or under CARB OBD II.
- 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.
