419-01B-2 Anti-Theft - Passive 419-01B-2 DESCRIPTION AND OPERATION Anti-Theft - Passive 2 1 E139165 Item Description 1 Passive anti-theft (PATS) transponder 2 PATS transceiver PATS The PATS is a passive system designed to increase the anti-theft security of the vehicle. The driver does not need to actively do anything to protect the vehicle. The PATS is activated automatically after the ignition is switched off. The PATS system uses specially encoded keys. If a valid key is inserted into the ignition lock cylinder and turned to position II, the code from the PATS transponder is received by the PATS transceiver. The code is then sent to the passenger junction box (PJB) which checks that a correct key has been inserted and communicates with the powertrain control module (PCM) to enable the engine to start. If the code received by the PATS transceiver does not agree with any of the codes programmed to the vehicle, or if errors occur in the PATS, the engine cannot be started. To indicate a concern in the PATS, the Vehicle immobiliser indicator glow in the instrument cluster.
