Passive Anti-Theft System (PATS) Transceiver

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, will send a message to the PCM to ground the starter relay solenoid coil and to also allow the fuel injectors to operate.
