Question

How to fix codes P1000, P1550, P1703, and P1780 on a 2007 Ford F150 Lariat?

Answer 1

I can't find any direct relation with the codes, the P1000 is an information code, it just means that there are other codes. I suggest trying to clear all codes first, driving your vehicle, and starting to diagnose the code that comes back first.
