About 2 weeks ago I had to jump my 2007 2500hd 4x4 (6.0 with 6 speed trans and electronic transfer switch) to start it. I then had a alert that my 4 wheel drive needs service?

Hello,

Since this issue begins after a jump start, it is possible that you might have a blown fuse.
Check the fuse box under the hood. There should be a 30A fuse for transfer case function.

I have attached the fuse diagrams for the under-hood fuse box.

Please let me know what you find.

Thank you.
