P1000 Code Ford: What Does It Mean and How to Fix It?

[Nicko]

Hey guys, I got this weird P1000 code on my Ford Mustang GT 2016. The car runs fine, but the code won’t go away. I’ve cleared it, but it just keeps popping up again. I read somewhere it has to do with readiness tests not being complete after a battery reset? Anyone know what’s up or how to fix this? Should I be worried or just ignore it?
