I took my first trip with the new VMSpc installed an I am more than happy with it...but I'm a big ol' geek anyway.
I'm having some gps issues but that's for a different forum.

I was getting some weird diagnostic codes and a can NOT seem to figure these out.....see below.

Any help would be appreciated. I have downloaded a few different CAT code lists but can't see to sort this out.

1998 CAT 3126 300HP
