Vehicle Theft Security: Description
The Vehicle Theft Security System (VTSS) is an available factory-installed option on this model. 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 the various components that are included in each of these subsystems of the VTSS.
Hard wired circuitry connects many of the VTSS components to each other through the electrical system of the vehicle.
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. In addition, the VTA for Export is available in two versions: base and premium. 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 provides perimeter vehicle protection by monitoring the vehicle doors, the tailgate, the rear flip-up glass and, for vehicles built for certain markets where it is required equipment, the hood. If unauthorized vehicle use or tampering is detected, these systems respond by pulsing the horn and flashing certain exterior lamps. The Export premium version of the VTA is only available in vehicles manufactured for sale in certain markets where it is required equipment. The Export premium version of the VTA provides the same perimeter protection features as the base version, but adds interior vehicle intrusion protection. The Export premium VTA also replaces the pulsing horn feature of the base version with an alarm siren as the audible deterrent, while retaining the flashing exterior lamps visual deterrent.
The VTA includes the following major components, which are described in further detail elsewhere in this service information:
- Body Control Module - The Body Control Module (BCM) is located on the Junction Block (JB) under the instrument panel. See ELECTRONIC CONTROL MODULES article.
- Combination Flasher - An electronic combination flasher is integral to the hazard switch located in the center of the instrument panel above the radio. See EXTERIOR LIGHTS article.
- Door Ajar Switch - A door ajar switch is integral to the latch of each door in the vehicle. See INTERIOR LIGHTING article.
- Door Cylinder Lock Switch - For North American vehicles only, a door cylinder lock switch is located on the back of the driver door lock cylinder. See DOOR CYLINDER LOCK SWITCH .
- Flip-Up Glass Ajar Switch - A flip-up glass ajar switch is integral to the rear flip-up glass latch, located on the top of the tailgate near the center. See INTERIOR LIGHTING article.
- Hood Ajar Switch - A hood ajar switch is located on the right inner fender side shield of vehicles built for sale in markets where it is required equipment. See HOOD AJAR SWITCH .
- Horn Relay - A horn relay is located on the Junction Block (JB) under the instrument panel. See HORN article.
- Intrusion Transceiver Module - An Intrusion Transceiver Module (ITM) is located near the center of the headliner in the passenger compartment of vehicles built for sale in markets where it is required equipment. See INTRUSION TRANSCEIVER MODULE .
- Security Indicator - A security indicator is located in the ElectroMechanical Instrument Cluster (EMIC) on the instrument panel in front of the driver side front seat. See INSTRUMENT CLUSTER article.
- Siren - An alarm siren is located on the front of the right front wheel house panel in the engine compartment of vehicles built for sale in markets where it is required equipment. See SIREN .
- Tailgate Ajar Switch - A tailgate ajar switch is integral to the latch for the tailgate in the vehicle. See INTERIOR LIGHTING article.
Sentry Key Immobilizer System - The Sentry Key Immobilizer System (SKIS) is available as a factory-installed option on this model. 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:
- Powertrain Control Module - The Powertrain Control Module (PCM) is located on the left inner fender shield in the engine compartment. See ELECTRONIC CONTROL MODULES article.
- Sentry Key Immobilizer Module - The Sentry Key Immobilizer Module (SKIM) is located beneath the steering column shrouds on the right side of the steering column. See ELECTRONIC CONTROL MODULES article.
- Sentry Key Transponder - The Sentry Key transponder is molded into the head of the ignition key. See TRANSPONDER KEY .
- SKIS Indicator - The Sentry Key Immobilizer System (SKIS) indicator is located in the ElectroMechanical Instrument Cluster (EMIC) on the instrument panel in front of the driver side front seat. See INSTRUMENT CLUSTER article.
