Believe it or not, GM has antitheft systems that will do the same thing when they mess up......so it's not just a Ford thing.
Oh and Chris, I've been a tech/mechanic for 27 years and an ASE master tech for 20 of those, and I've NEVER had a scanner tell me what's broke.
They can steer you in the right direction or lead you astray, but it's up to a real "tech" know the difference and find what's broke......jmo
