The problem is that you went to far on tire size in your ECM and now you need to have your abs module reflashed so they arent out of sync. I could run up to a 34.5 tall tire in my ECM before it popped and abs code. Unless you actually have an abs problem 
if so tell me what the code is
if so tell me what the code is
Well its a guy my dad works with, but he has 37s on it and I put the size in at 36. Ill have to find out what the code says or if it even has an actual code
You have to reflash the ABS module to a Kodiak tire size. I can't remember the size exactly. You'll have to have a dealership do it with a Tech 2 (good luck). I pulled the fuse so the light and dinger bell goes off as soon as I start the truck. I use my remote start so all that noise is done by the time I get in.
