Section 45 (Vehicle Theft Security (Service Information)): Description: Description: Notes

The Vehicle Theft Security System (VTSS) is an available factory-installed option on this vehicle. The 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:

• Body Control Module (BCM)  - The BCM is located in the interior compartment in the right kick panel. The BCM provides the VTA system logic, driver and passenger door ajar switch status, hood ajar (export) and power lock switch status. Refer to MODULE, BODY CONTROL, DESCRIPTION .
• Instrument Cluster  - The Instrument Cluster (IC) is also known as the Cab Compartment Node (CCN). The IC/CCN is located in the instrument panel above the steering column opening, directly in front of the driver. The IC provides the security indicator. Refer to DESCRIPTION .
• Powertrain Control Module  - The Powertrain Control Module (PYGMY) provides the SKIS engine control logic. Refer to MODULE, POWERTRAIN CONTROL, DESCRIPTION .
• Radio Frequency Hub (RF-Hub)  - The Radio Frequency Hub (RF-Hub) provides ignition switch status by way of the Keyless Ignition Node (KIN). The RF-Hub broadcasts that message over the CAN Bus network. The Remote Start logic is contained in the RF-Hub and the Remote Start Antenna is connected directly to it. Refer to MODULE, RADIO FREQUENCY (RF HUB), DESCRIPTION .

Except for the Sentry Key transponders integral to the FOB with Integrated Key (FOBIK) which rely upon Low Frequency (LF) communication, hard-wired circuitry connects the VTA and SKIS components to the electrical system of the vehicle. These hard-wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system, and to the SKIS components through a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, procedures for proper wire and connector repair, wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices, and grounds.
