Vehicle Theft Security System - Description

DESCRIPTION

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. Description and Operation.
- 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. Instrument Cluster - Description.
- Powertrain Control Module - The Powertrain Control Module (PYGMY) provides the SKIS engine control logic Description and Operation
- 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.Radio Frequency Module (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.

VEHICLE THEFT ALARM

The VTA is available in three different configurations for this vehicle: One configuration is designed for vehicles manufactured for sale in North America; while, the other two configurations are designed for vehicles manufactured for sale in markets outside of North America, also referred to as export markets within the context of this service information. All vehicles equipped with VTA are also equipped with the Remote Keyless Entry (RKE) system and the Sentry Key Immobilizer System (SKIS), regardless of their market destination.

The North American and export base version of the VTA system provide perimeter vehicle protection by monitoring the vehicle doors, the ignition switch, the liftgate, and the hood for vehicles built for certain markets where it is required equipment. On the premium export version it also monitors vehicle tilt and motion. If unauthorized vehicle use or tampering is detected, these systems respond by pulsing the vehicle horn. The premium export version will sound a siren. The siren is located in the left front corner on the radiator support. This produces an audible deterrent. Both of these systems will also flash certain exterior lamps which produces a visual deterrent.

The VTA includes the following major components, which are described in further detail elsewhere in this service information:

- Door Ajar Switches - A door ajar switch is integral to the door latch mechanism of each front and rear door.
- Hood Ajar Switch - A hood ajar switch is located in a bracket on the right inner fender side shield of vehicles built for sale in certain export markets where it is required equipment.
- Liftgate Ajar Switch - A liftgate ajar switch is integral to the latch for the liftgate in the vehicle. Latch - Removal.
- Security Indicator - A security indicator is integral to the Instrument Cluster (IC) (also known as the Cab Compartment Node/CCN). Instrument Cluster - Description.

SENTRY KEY IMMOBILIZER SYSTEM

The Sentry Key Immobilizer System (SKIS) is standard on all vehicles equipped with the Radio Frequency Hub. The SKIS provides passive vehicle protection by preventing the engine from operating unless a valid electronically encoded FOBIK is detected in the vehicle interior.

The SKIS includes the following major components, which are described in further detail elsewhere in this service information:

- Security Indicator - A security indicator is integral to the Instrument Cluster (IC) (also known as the Cab Compartment Node/CCN). Instrument Cluster - Description.
- Sentry Key Transponder - The Sentry Key transponder is integral to the FOB with Integrated Key (FOBIK), which also includes an integral Remote Keyless Entry (RKE) transmitter and an integral mechanical valet key Transponder Key - Description.
- Radio Frequency Hub - The Radio Frequency Hub (RF-Hub) is located above the headliner at the liftgate opening. The RF-Hub is hardwired to the Keyless Ignition Node (KIN). The RF-Hub performs all of the same functions performed by a Wireless Control Module (WCM) or a Wireless Ignition Node (WIN) and the Passive Entry Module used on other vehicles. Radio Frequency Module (RF Hub) - Description.
- Powertrain Control Module - The Powertrain Control Module (PYGMY) provides the SKIS engine control logic . Description and Operation
- 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. Description and Operation.
