Ford Pats (Passive Anti Theft System) Initialization With The 2534 Global Programmer

There are five types of PATS implementations from Ford (A, B, C, D, E). Refer to Table 1 (page 11) to identify what type of PATS your vehicle is equipped with. PATS initialization is generally performed after programming.
The A or D version of PATS does not store the key information in the PCM, therefore NO PATS KEY RELEARN IS REQUIRED after programming.
The B or C versions of PATS store the key information within the PCM and MUST be transferred to the new PCM, or relearned on the vehicle after the new PCM is installed.
The E version of PATS also stores the key information within the PCM, but CANNOT be transferred to the new PCM. This type MUST be relearned on the vehicle after the new PCM is installed.
Note: If you are just updating the existing PCM calibration with an update calibration, you must select the MODULE REPROGRAMMING function (not Programmable Module Installation). Doing this will insure you retain the existing PATS key information.
IF REPROGRAMMING AN UPDATED CALIBRATION TO AN EXISTING PCM (ALL PATS TYPES)
The Module Reprogramming selection MUST be selected, not reprogram and install (this will avoid a key relearn procedure).
If REPLACING OR INSTALLING A NEW PCM (B, C TYPES ONLY)
The Programmable Module Installation selection MUST be selected. To transfer your PATS key information to the new PCM, your original PCM must be connected to the global programmer first. This must be done to avoid a key relearning procedure. If the original is unavailable, a PATS key relearn procedure must be performed after the PCM is installed on the vehicle.
