Vehicle Theft Security System (VTSS): Notes

Vehicle Theft Security System (VTSS) monitors vehicle doors, hood, trunk key cylinder and ignition for unauthorized operation/entry. When VTSS is set, operation of the integrated garage door opener is disabled. When alarm is triggered, the horn will sound for 3 minutes and the parking lights will flash for 15-18 minutes.

When an unauthorized entry into vehicle occurs, the Body Control Module (BCM) signals Powertrain Control Module (PCM) via CCD bus that it is not okay to start the engine. The PCM then "zeros out" the pulse width of the fuel injectors, thus preventing the engine from starting (start/stall condition). The engine will NOT start until VTSS is disarmed.
