Of course, the tire pressuere must be checked and equal before making any initiation. My opinion is that the car is checkning the number of rotations in a certain time or distance before you park the car and do the initiation.
So I have found out that it works best if you find a very straight street with no traffic, maybe minimum 500 meters. Maybe in some industrial area. You pull over the car to the side and park, almost without using the steering wheel, like keep the straight line of the street. Then the Civic has a good record of the number of rotation of each wheel.
Make the initiation! And it works.
