Vehicle Theft Security - Description
DESCRIPTION
The Vehicle Theft Security System (VTSS) is an available factory-installed feature on this vehicle. The VTSS is comprised of two primary subsystems: the optional Vehicle Theft Alarm (VTA) and the standard 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 - The ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) provides security indicator control. Instrument Cluster - Description.
- Powertrain Control Module - The Powertrain Control Module (PCM) provides the SKIS engine control logic.
- Totally Integrated Power Module (2) - The Totally Integrated Power Module (TIPM) is located in the engine compartment, near the battery. The TIPM monitors door, swing gate and hood ajar switch status and provides the VTA system logic. Totally Integrated Power Module (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. 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 the use of 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, proper wire and connector repair procedures, 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. 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 system provide perimeter vehicle protection by monitoring the vehicle doors, the ignition switch, the swing gate 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 vehicle horn as an audible deterrent and flashing certain exterior lamps as a visual deterrent.
The export premium version of the VTA system 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 enhances the pulsing horn feature of the base version with an alarm siren as the audible deterrent, while retaining the flashing exterior lamps as the visual deterrent.
The VTA includes the following major components, which are described in further detail elsewhere in this service information:
- Door Ajar Switches (8) - A door ajar switch is integral to the door latch mechanism of each front and rear door. Latch - Removal.
- Hood Ajar Switch (1) - A hood ajar switch is located in a bracket on the inboard side of the left front fender load path beam within the engine compartment of vehicles built for sale in certain export markets where it is required equipment.
- Intrusion Module (5) - An intrusion module is located on a bracket on the lower instrument panel reinforcement beneath the driver side instrument panel in the passenger compartment of vehicles built for sale in certain export markets where it is required equipment.
- Intrusion Sensors (7, 9 and 10) - Two (two-door vehicles) or three (four-door vehicles) microwave intrusion sensors are located within the passenger compartment of vehicles built for sale in certain export markets where it is required equipment. One sensor is located within the lower center stack area of the instrument panel, another is located within the rear of the center floor console (four-door vehicles only) and the third is located within the swing gate.
- Swing Gate Ajar Switch (11) - A swing gate ajar switch is integral to the latch for the swing gate in the vehicle. Latch - Removal.
- Security Indicator (4) - A security indicator is integral to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). Instrument Cluster - Description.
- Siren (3) - An alarm siren is located on the right component tray (gasoline engine) or on the inboard side of the left front fender load path beam (diesel engine) within the engine compartment of vehicles built for sale in certain export markets where it is required equipment.
SENTRY KEY IMMOBILIZER SYSTEM
The Sentry Key Immobilizer System (SKIS) is standard factory-installed equipment on this vehicle. 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 Remote Entry Module (6) - The Sentry Key REmote Entry Module (SKREEM) (also known as the Wireless Control Module/WCM) is located on the right side of the steering column near the ignition lock cylinder housing and an integral molded plastic antenna ring circles the ignition lock cylinder like a halo. The SKREEM and its antenna are concealed beneath the shrouds on the steering column. Sentry Key Immobilizer Module (SKREEM) - Description.
- Sentry Key Transponder - The Sentry Key transponder is contained within the Remote Keyless Entry (RKE) transmitter integral to the head of the ignition key. Transponder Key - Description.
