What is the passive anti-theft system on a Ford Fiesta?
The Ford Fiesta is equipped with a passive anti-theft system (PATS) that helps prevent unauthorized access to the vehicle. This system is designed to immobilize the engine if the correct key is not used, providing an effective deterrent against theft.
How the Ford Fiesta's Passive Anti-Theft System Works
The PATS on the Ford Fiesta is a security feature that uses a transponder embedded in the ignition key. When the key is inserted into the ignition, the vehicle's electronic control unit (ECU) reads a unique code from the transponder. If the code matches the one stored in the ECU, the engine is allowed to start. If the code does not match, the engine will not start, effectively immobilizing the vehicle.
The PATS system is considered a "passive" anti-theft system because it automatically activates when the vehicle is locked and the key is removed from the ignition. This means the driver does not need to manually activate the system, as it is always on and ready to prevent unauthorized access.
Key Components of the Ford Fiesta's PATS
- Transponder Key: The ignition key contains a small radio frequency identification (RFID) transponder that transmits a unique code to the vehicle's ECU.
- Antenna Coil: Located around the ignition cylinder, the antenna coil detects the presence of the transponder key and reads the code it transmits.
- Electronic Control Unit (ECU): The vehicle's ECU compares the code received from the transponder key to the code stored in its memory. If the codes match, the ECU allows the engine to start.
- Immobilizer: If the codes do not match, the immobilizer feature in the ECU prevents the engine from starting, effectively immobilizing the vehicle.
The PATS system on the Ford Fiesta is a robust security feature that helps protect the vehicle from theft. By requiring a unique transponder code to start the engine, the system makes it much more difficult for thieves to steal the vehicle.
