Anti-Theft Systems: Description

Vehicle Theft Security System (VTSS) monitors vehicle doors, ignition switch, power door lock circuits and trunk key cylinder to determine if Body Control Module (BCM) should sound horn, flash interior lights and headlights, and disable ignition system. BCM inputs for VTSS are divided into 2 sections: the trunk area and the passenger compartment.

System is passively armed by opening door, locking door using power door locks and closing door. System will arm within 15 seconds if no monitored systems are activated. System can also be armed using Remote Keyless Entry (RKE) transmitter or ignition key. System will not arm if manual door lock knobs are used to lock door(s). VTSS system uses a Light Emitting Diode (LED) to indicate when the system is armed. LED is located in instrument cluster.
