OBD not ready and Fails the inspection

[EVO]

I'm going to sound off on this because I had all kinds of codes popping up after I changed the battery. I had to clean both the positive and negative post clamps INSIDE and OUT so there was no corrossion left inside and wire brush those terminals till you see shiny metal. Install battery and viola all those nasty codes went away. Every time I hear battery replacement and electrical problems I go after the battery as it was the last thing I mucked with before my dashboard went wonky! Good luck!!
