WARNING: When performing drive cycle N on a public road, pay sufficient attention to the traffic condition and give the highest priority to safe driving.
  1. Check the data in condition column of table by using the Subaru Select Monitor or general scan tool.
    NOTE:
  2. While the conditions in the list are satisfied, race the engine at the speed of approx. 2, 500 rpm for 40 seconds or more.
  3. Start the vehicle, then accelerate the vehicle to 50 km/h (31.1 MPH) or more.
  4. When the speed reaches 50 km/h (31.1 MPH) or more, release the accelerator pedal, the brake pedal and the clutch pedal (MT model) to decelerate the vehicle without shifting the gear. At this time, select an appropriate gear beforehand so that the engine speed can decrease from 2, 500 rpm to 1, 900 rpm for 5 seconds or more.
    NOTE:
    • The vehicle speed does not matter so long as the engine speed can maintain from 2, 500 rpm to 1, 900 rpm for 5 seconds or more.

      Example: On a downhill grade, it can be performed with a low speed gear and at a low vehicle speed.

    • When it is performed with the electrical load such as the air conditioner, etc. turned OFF or the vehicle driven on a downhill grade, the engine speed decreases slowly. Therefore, the continuous time can be maintained easily.
  5. Bring the vehicle to a stop in a safe place, and idle it for 5 minutes or more.
    NOTE: Driving method while vehicle is driven to a stop at safe place is not restricted.
  6. With the vehicle idling, read the temporary diagnostic code of DTC using Subaru Select Monitor or general scan tool.
