I don't know if I would say I recommend, but I have no reservations about it.@Snakebitten do you recommend resetting the pcm or the pcm all adaptations along with the transmission tables?
Truth is, if your battery was dead, or if it was disconnected for any kind of procedure as benign as a stereo system install, your PCM might experience "a reset".
And often times one of the troubleshooting techniques for addressing issues with a vehicle, is to do a "kam reset", (which is "keep alive memory" reset) It is just another phrase for these tables we are discussing.
I think of it this way.....
When you buy a computer or a smartphone, the first thing you experience is what's call the "out of box" experience. It's all that routine that you go through that only is required once.
But if I was going to give the computer to one of my children, I would reset it and then they would experience the out of box routine because the computer would have its" tables" wiped.
It's a lousy comparison in some ways because the pcm doesn't require you to participate in the out of box routine. But it does have that routine itself. It experienced it the first time Ford woke it up on the assembly line.
It experienced it everytime its firmware was upgraded. (which is fairly often on this new OTA platform design) And as I mentioned earlier, it can and will experience it if/when it experiences a 12V disruption of more than a few minutes.
I actually find it appealing to think that I can easily, almost effortlessly, wipe the slate clean and let the truck be digitally born again, so to speak.
I assure you that I'm just an amateur at all this though. So please don't think otherwise. The real experts will have rolled their eyes a few times at this post I'm sure.
Afterall, there's data in the pcm (or some module) that doesn't "reset" regardless of what happens. (mileage for example) So my analogy(s) are not accurate.
