No, a pcm, bcm, or ecm will not reset itself while driving. On the otherhand it will do checks when you start the car to make sure everything is operating properly. If something is not it will light up the infamous check engine light.(pcm)
There is nothing for it to reset when you replace the battery. It does not loose it's memory when the battery is disconnected anymore than a computer in your home looses it's memory when you unplug it from the wall outlet. Therefore there is nothing to reset.
