I would think that what ever repairs or component replacements any repair depot may make in order to guaranty the product is 100% repaired to meet or exceed OEM performance specification is their business. However, is the repair depot certified by Ford to make factory authorized repairs which would be an indicator that they have the original performance requirements in order to know what is required to meet OEM minimum specifications. I can think of NO reason why a reputable repair depot would conceal or hide any OEM certification, any procedure/process and specialized equipment they implement to confirm what their guaranty claims in meeting 100% OEM specification. But of course... if they actually don't do anything but replace parts!

With the repair of complex electronic circuit boards the real value of any repair depot comes into consideration with a guaranty of 100% TEST coverage to meet or exceed OEM performance specifications.
