Vehicle Theft Security System: Notes

The Vehicle Theft Security System (VTSS) module is located behind glove box. VTSS monitors vehicle doors, hood, trunk key cylinder and ignition for unauthorized operation/entry. 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 VTSS module 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.
