Vehicle Theft Security System

When the VTSS is armed, it will monitor the ignition switch status, ajar switches for the vehicle doors and decklid. Also monitored is a decklid security switch (knockout) for the cylinder lock. If the alarm is tripped, it will sound the vehicles horn, flash the exterior lamps and the VTSS indicator located in the instrument cluster.

Arming the system is accomplished by locking the doors with the door lock switch following a normal exit sequence of opening the door pressing the power lock button and closing the door, by using the driver door cylinder lock switch or by pressing the RKE lock button. After all the doors are closed, the VTSS indicator will flash quickly for sixteen-seconds indicating the pre-arm process, after which it will flash at a slower rate indicating the system is armed. If during the pre-arm process a door is opened, the ignition is turned to the Run/Start position or if the RKE module receives an unlock request the system will automatically be disarmed. If the VTSS indicator stays on steady during prearm, it is an indication of an open decklid security switch sense circuit.

Disarming can be accomplished with a RKE unlock, turning the ignition on with a valid Sentry key or unlocking the vehicle with the driver door cylinder lock. All of the switches for the VTSS system can be monitored using the DRBIII®. The DRBIII® is also useful to determine the cause of a customer complaint of the alarm going off with no apparent reason.
