Can anyone identify what this fuse is for?

I looked in the owners manual and it doesn’t mention it or reference it, I also looked around the cover. Does anyone know what this 5A fuse under the battery cover is for?

looks like it goes to the battery sensor module (regulated voltage control)
also learned something new while searching, the 2021's now have a electronic brake pad wear sensor isn't that nifty

*also that fuse will be known as fuse 98 which is conveniently left out of the owners manual

Just when you’ve think you’ve heard it all...you gotta break out the electronic brake pad wear indicator. Haha! What’s next?

Sorry...”sensor.”

Intresting. Thanks for the Schematic I was hoping it was feedback voltage for auto stop only and not the whole ECU. Yeah the Info screen on the gauge cluster will give you % of life on brake pads. It’s clever but I have to wonder how accurate it is and what happens years down the road when I swap brake pad with another manufacturer.

if you are looking for the autostop schematics all of that stuff can be found in the gm upfitter guide, as I was scrolling thru I saw the autostop diagrams as well, if you are trying to disable it or something just be aware all this new tech has several redundancies built in if you mess with something it will probably throw a code or "service such and such" on the screen, all these things self check themselves it may work for a minute and then it goes thru a check and bam code!
