Passive Anti-Theft System (PATS) Transceiver

WARNING: This page is about a different variant/trim than selected.

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 TCM to allow the eCVT to start the engine and sends a message to the PCM to allow the fuel injectors to operate.
