Vehicle Theft Security System (VTSS)
The Vehicle Theft Security System (VTSS) is part of the Body Control Module (BCM). The BCM monitors the vehicle doors, hood, and the ignition for unauthorized operation. The alarm activates by sounding the horn, flashing the headlamps and the VTSS indicator lamp. The VTSS does not prevent engine operation, this is done with the Sentry Key Immobilizer Module (SKIM). The VTSS indicator lamp will flash for approximately 15 seconds during the arming process. If there is no interruption during the arming process, upon completion the VTSS indicator lamp will flash at a slower rate. When the BCM receives an input to trigger the alarm, the BCM will control the outputs of the headlamps, horn, and VTSS lamp for approximately 15 minutes.
