Section 59 (Vehicle Theft Security System (Service Information)): Description: Description: Notes

WARNING: This page is about a different car, the 2010 Dodge Avenger and 2010 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

The Vehicle Theft Security System (VTSS) is comprised of two primary subsystems: Vehicle Theft Alarm (VTA) and Sentry Key Immobilizer System (SKIS). The VTA is an active system that provides visual and audible responses as deterrents to and warnings of unauthorized vehicle tampering. The SKIS is a passive system that effectively immobilizes the vehicle against unauthorized operation. Following are paragraphs which describe these subsystems of the VTSS.

Certain functions and features of the VTSS rely upon resources shared with or controlled by other electronic modules in the vehicle over the Controller Area Network (CAN) data bus. Other modules that may affect VTSS operation are:

ElectroMechanical Instrument Cluster (EMIC) - Also sometimes referred to as the Cab Compartment Node (CCN). Driver and passenger front and rear doors, and liftgate ajar switch status. VTA system logic. Security indicator control. Refer to Electrical/Instrument Cluster - Description .
Powertrain Control Module (PCM) - SKIS engine control logic. Refer to Electrical/Electronic Control Modules/MODULE, Powertrain Control - Description .
Steering Column Module (SCM) -. Refer to Electrical/Electronic Control Modules/MODULE, Steering Column - Description .
Totally Integrated Power Module (TIPM) - Hood ajar switch status (export only). Exterior lighting system and horn system control. Refer to Electrical/Power Distribution/MODULE, Totally Integrated Power (TIPM) - Description .

Except for the Sentry Key transponders, which rely upon Radio Frequency (RF) communication, hard wired circuitry connects the VTA and SKIS components to the electrical system of the vehicle.
