Vehicle Theft Security System
The Vehicle Theft Security System (VTSS) protects the vehicle from theft by monitoring door-ajar switches, the ignition circuit and trunk/liftgate ajar for unauthorized entry. If a switch or sensor is triggered, the horn blows intermittently and turn signal lamps flash for up to three minutes after that, the turn signal lamps continue to flash for up to 15 minutes to deter theft of the vehicle. If the alarm was triggered but the warning signals have timed out, the park and tail lamps flash three times instead of the normal twice when unlocking the vehicle with the RKE to alert the driver. Locking the doors in any of the following ways automatically arms the VTSS:
- With an interior power lock switch.
- With a valid RKE transmitter.
The Vehicle Theft Security System (VTSS) is designed to provide perimeter protection against unauthorized use or tampering by monitoring the vehicle door and liftgate ajar circuits, the power lock and unlock circuits, and the ignition switch circuit. If unauthorized use or tampering is detected, the system responds by pulsing the horn for up to about three minutes and flashing the hazard warning lamps for up to about eighteen minutes.
The VTSS 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.
- Front Control Module - The Front Control Module (FCM) is integral to the Integrated Power Module (IPM). The FCM/IPM is located in the engine compartment, near the battery and the Power Distribution Center (PDC) (Refer to ELECTRICAL/POWER DISTRIBUTION - DESCRIPTION) .
- Horn Relay - The horn relay is located in the Power Distribution Center (PDC) in the engine compartment near the battery. (Refer to HORN SYSTEM- SERVICE INFORMATION ).
- Ignition Switch - The ignition switch is located on the steering column in the passenger compartment. (Refer to IGNITION SWITCH - DESCRIPTION in STEERING .
- Instrument Cluster - The ElectroMechanical Instrument Cluster (EMIC) is also known as the Cab Control 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 (Refer to ELECTRICAL/INSTRUMENT CLUSTER - DESCRIPTION) .
- Liftgate Ajar Switch - Wagon only - A liftgate ajar switch is integral to the latch mechanism of the liftgate.
- Security Indicator - The security indicator is integral to the instrument cluster (Refer to ELECTRICAL/INSTRUMENT CLUSTER - OPERATION) .
