How To Tell If You Have A Ford PATS Issue
When you replace your PCM in a Ford/Lincoln/Mercury, the process is not plug and play if your vehicle does have Ford's OEM security - Passive Anti Theft Security or PATS. Most of these vehicles do have PATS and there are some additional steps which will need to be executed. Sometimes you can do these on your own. Sometimes you will need special software to complete this process. It will just depend on which vehicle you have.
Ford also requires you have two unique keys to update the PATS system. So if you only have one key, or if you have a cloned key, you will need to be sure you have a second unique key (not cloned) before you can update the PATS system.
