Passive Anti-Theft System (PATS) Transceiver

WARNING: This page is about a different car, the 2010 Mercury Milan and 2010 Ford Fusion. 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 ID code and sends data to the IPC  . The IPC  validates the code, and if it is the correct code, sends a message to the TCM  to enable the engine and the electric drive.
