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:

  1. With an interior power lock switch.
  2. 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:
