Usually the OBD-II drive cycle test clears after driving various roads. The test looks for all kinds of different driving conditions (highway, stop and go, etc.). It will automatically clear once the different conditions have been seen. Since it is looking for various road conditions its difficult to pinpoint a mileage when it clears--it all depends on where and how you drive it.
