Vehicle Theft Security - 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:

- Totally Integrated Power Module (TIPM) - The TIPM is located in the engine compartment, near the battery. The TIPM provides the VTA system logic, driver and front passenger door ajar switch status, and power lock switch status Totally Integrated Power Module (TIPM) - Description.
- ElectroMechanical Instrument Cluster - The ElectroMechanical Instrument Cluster (EMIC) is also known as the Cab Compartment Node (CCN) in this vehicle. The EMIC/CCN is located in the instrument panel above the steering column opening, directly in front of the driver. The EMIC provides the security indicator Instrument Cluster - Description.
- Powertrain Control Module - The Powertrain Control Module (PCM) provides the SKIS engine control logic Powertrain Control Module - Description.
- Wireless Ignition Node - The Wireless Ignition Node (WIN) provides ignition switch status Wireless Ignition Node Receiver - 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, further details on 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 two different configurations for this vehicle: One configuration is designed for vehicles manufactured for sale in North America; while, the other configuration is 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. If unauthorized vehicle use or tampering is detected these systems respond by pulsing the vehicle horn as an audible deterrent and flashing certain exterior lamps as 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 Liftgate Latch - Removal.
- Security Indicator - A security indicator is integral to the ElectroMechanical Instrument Cluster (EMIC) (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 a Wireless Ignition Node (WIN). Vehicles equipped with the Vehicle Theft Alarm (VTA) are also equipped with SKIS. The SKIS provides passive vehicle protection by preventing the engine from operating unless a valid electronically encoded key is detected in the ignition lock cylinder.

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 ElectroMechanical Instrument Cluster (EMIC) (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.
- Wireless Ignition Node - The Wireless Ignition Node (WIN) is located behind the instrument panel, and is partially concealed by the ignition switch bezel. The remainder of the WIN including its mounting provisions and electrical connections are concealed within the instrument panel. The WIN contains the integral ignition switch and performs all of the same SKIS functions performed by a Sentry Key Immobilizer Module (SKIM) used on prior vehicles Transponder Key - Description.
