BCM parasitic draw

I have a 2010 SS, and have a parasitic draw issue. I have tested and isolated it to the circuit fed by fuse f14 in the trunk, which is the BCM if I read the diagram on Chilton right. If I don't pull that 5 amp fuse the battery will die over a 2 day period of sitting. Has anyone else experienced this? Is this indicative of a bad BCM? I also hear about 5 loud tapping noises in rapid succession within a few minutes of starting the car, emanating from the trunk area. Is there a relay there that sticks or something?

All the fuses in the trunk are hot all the time, any aftermarket stuff tapped into the fuse box like an aftermarket amp or lights? Or maybe the mylink amp isn’t shutting off? Clicking might be fuel pump? These things can be impossible. I had a parasitic draw on my vette I only “fixed it” by trading it in.

It's the only 5 amp fuse in the trunk I see, unless I am not understanding something?

No nothing like that.

Well, look at the rear view camera wiring schematic, see where it goes. I believe that's what RVC is. I use Alldata, but I wasn't looking at convertible which it looks like that is. Alldata didn't show any f14 in the rear for non convertible.

I believe it is actually regulated voltage control.
