Solution: Ali, I follow the step to pull the DTC it's read 16 Faulty link between PATS Module and EECV, But is there any other way from going to Dealer? , Are you using a copy of the original key you need to use the original key for the car Antitheft and Alarm Systems: Description and Operation ANTI-THEFT The passive anti-theft system (PATS) uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code, with over 72 million billion combinations. Each encoded ignition key must be programmed into the vehicle powertrain control module (PCM) before it can be used to start the engine. There are special diagnostic procedures that must be carried out if new encoded ignition keys are to be configured. The encoded key is larger than a traditional ignition key. The key does not require batteries and should last the life of the vehicle. The transceiver module communicates with the encoded ignition key. This module is located behind the steering column shroud and contains an antenna connected to a small electronic module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the PCM. The control functions are contained in the PCM. This module carries out all of the PATS functions such as receiving the identification code from the encoded ignition key and controlling engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to ON or START. The PATS function uses the PCM to enable or disable the engine. All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start. PATS uses a visual theft indicator located on top of the instrument panel. This indicator will prove out for three seconds when the ignition switch is turned to ON or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to ON or START. PATS also "flashes" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent. The PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related no-start issues. The PATs key is used on the following Ford family trucks and suvs: FORD: 1996-2001 MUSTANG, TAURUS 1998-2000 CONTOUR 1998-2001 CROWN VICTORIA 2000-2001 FOCUS 2002 THUNDERBIRD 1997-2001 EXPEDITION 1998-2002 EXPLORER 1999 F-250 LD 1999-2001 F-150, RANGER, WINDSTAR 2000-2001 EXCURSION 2001 ESCAPE LINCOLN: 1997-1998 MARK VIII 1998-2001 CONTINENTAL, TOWN CAR 2000-2001 LS 1998-2001 NAVIGATOR 2002 BLACKWOOD MERCURY: 1996-2001 SABLE 1998-2000 MYSTIQUE 1998-2001 GRAND MARQUIS 1999-2001 COUGAR 1998-2002 MOUNTAINEER Additionally, PATs can be found on the follow Ford family cars and mini-vans: 1998-up Contour 1997-up Crown Victoria 1999-up Escort 2000-up Focus 1996-up Mustang and Taurus 1998-up Windstar 1998-up 2000-up Lincoln LS 1998-up Lincoln Mark VIII, Lincoln Continental and Lincoln Town Car 1997-up Mercury Grand Marquis 1998-up Mercury Mystique 1996-up Mercury Sable Following are the instructions for programming a blank key (you must have at least one working key for this procedure).
