well when you, for example, change tires on your Acura, you will not need to relearn it. It will relearn itself as long as it has the original sensors in it. Thats mainly because it does not have sensor location in the system. It only tells you that one of the four tires are low.most Vehicles with location sensitive sensors need to be relearned almost every time they change tires or have a rotate. If you keep your original sensors, you'll be fine, but if you are getting wheels and tires with ILX sensors already in them, You will be ok as well, you will just more than likely have to go somewhere, and have them relearn the car to the new sensors.
