Passive Anti-Theft System (PATS) Transceiver

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The PATS  transceiver is located under the steering column shroud and communicates with the encoded ignition key. During each vehicle start sequence, the PATS  transceiver reads the encoded ignition key identification code and sends data to the IC  . The IC  validates the code, and if it is the correct code, the IC  sends a message to the PCM to ground the starter relay solenoid coil and allow the fuel injectors to operate.
