Vehicle Theft Alarm System: Notes

The Vehicle Theft Alarm (VTA) module is located behind glove box. it 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 VTA module signals engine controller (via CCD bus) that it is not okay to start the engine. The engine controller 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 vehicle theft alarm system is disarmed.
