Vehicle Theft Security System: Notes

The vehicle theft security system (VTSS) is controlled by the body control module, which monitors vehicle doors, liftgate, liftglass and the ignition for unauthorized operation. The alarm activates by sounding the horn, flashing the headlamps, hazard lamps, and the VTSS indicator lamp.

The VTSS does not prevent engine operation, this is done with the sentry key immobilizer module. Passive arming occurs upon normal vehicle exit by removing the ignition key, opening the driver door, locking the doors with the power lock, and closing the driver door or locking the doors with RKE. The indicator lamp on the dash will flash for 15 seconds, showing that arming is in progress. If no monitored systems are activated during this period, the system will arm and the indicator will flash at a slower rate.

When something triggers the alarm, the system will signal the headlamps, park lamps, and horn for about 18 minutes. For complaints about the theft alarm going off on it's own, use the DRBIII(R) and select THEFT ALARM, VTSS then MONITOR DISPLAY and read the ALARM TRIPPED BY status.
