PATS Transceiver

WARNING: This page is about a different car, the 2009 Ford Mustang. 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 PCM. The PCM validates the code, and if it is the correct code, will ground the starter relay solenoid coil and will also allow the fuel injectors to operate. Refer to Passive Anti-Theft System (PATS) Transceiver .
