Anti-Theft Systems - Passive: Description

Passive anti-theft system is available on 2.5L equipped vehicles. The system is passive in that it does not require any activity from the user. System uses radio frequency identification technology to verify if proper key is being used to attempt to start the vehicle.

During each starting sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the PATS module. If the key's identification code is programmed into anti-theft system, vehicle is capable of starting. If key's identification code is incorrect or missing, vehicle is prevented from starting.

PATS vehicle protection system consists of PATS module, theft indicator light, transceiver module, encoded ignition key, module communications network and Data Link Connector (DLC). PATS has self-diagnostic capabilities.
