What is the Pats system on a car?
Passive Anti-Theft Systems (PATS), also called Ford Securilock, is a vehicle security feature introduced on 1996 and later Ford vehicles. When replacing the Powertrain Control Module (PCM) on a PATS-equipped vehicle, a parameter reset or relearn procedure must be performed after the PCM is installed.
Where is the PATS system located on a Ford?
Over the years, Ford has located the PATS module in different places; • In some vehicles, it’s built into the instrument cluster • On some models it’s a separate module. • On some late model vehicles, the PATS module is located behind the steering column shroud and contains an antenna connected to a small electronics module.
Where is the Pats transceiver located on a car?
The PATS transceiver is mounted on the ignition lock cylinder housing and is connected to the PATS control module. The transceiver energizes the transponder key electronics through the key’s circular antenna. The PATS transceiver receives data from the control module through the transmit Tx signal.
Where is the key code stored in the PATS system?
The key code data is stored in the PATS control module. The PATS control module compares the received key code and validates or rejects the key code. If the key code is correct, the PATS control module sends a signal to the PCM to enable the fuel pump and injectors.
How does the key code work on the Ford Pats?
Up to 16 keys can be programmed. The transceiver sends the key code signal via a hardwired connection to the control module. At each start sequence, the PCM power the fuel pump and injectors until the engine runs for 1 second. Within that 1 second period, the PATS Control Module must determines if the key code is valid.
