Fuse to reset PCM

I can't remember, and cant find using search (Google and OS) the fuse to pull to reset the PCM instead of having to disconnect the negative battery cables. As most all of you know, disconnecting and reconnecting the negative battery cable on our trucks puts the vent actuators through a torturous cycle that a lot of times ends up breaking them.

The Roadie is on business trip and unable to help at the moment, but I was wondering if anyone else remembers/knows which fuse it is I'm referring to?

Any help would be greatly appreciated!

These pages are from the owner's manuals. I think you should be able to take it from here... :yes: (may be helpful to fill out the rest of your profile so we know what vehicle you're working with)

If you have a meter handy, you can test both fuses to see which is hot 24/7, and pull the appropriate one(s). If not, pull both...
