Howdy all,
This has me baffled, Tractor 90C case/Farmall has the alert light on and the code 3999, I can't find what this code is anywhere. Yesterday I was loading hay and another code with symbol came on that put tractor into limp mode.
It was a code that said DEF was contaminated. This also made the original 3999 code go away. I drained a put in new DEF and it eventually cleared and the tractor would work again but the original !with 3999 came back.
This is a tractor I recently bought and I'm not that familiar with it yet.
Thanks for any help.
