Vehicle Theft Security System
WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
Vehicle Theft Security System (VTSS) monitors vehicle doors, hood, trunk key cylinder and ignition for unauthorized operation/entry. When alarm is triggered, the horn will sound for 3 minutes and the parking lights will flash for 15-18 minutes.
When an unauthorized entry into vehicle occurs, the VTSS module signals Powertrain Control Module (PCM) through the Programmable Communication Interface (PCI) multiplex system (bus) that it is not okay to start the engine. The PCM then "zeros out" the pulse width of the fuel injectors, thus preventing the engine from starting (start/stall condition). The engine will NOT start until VTSS is disarmed.
