System Description

THEFT DETERRENT SYSTEM DESCRIPTION
The theft deterrent system is designed to deter vehicle break-ins and theft. If an attempted break-in or theft is detected, the vehicle horns and security horn will sound, the headlights, taillights and room light will illuminate and the hazard warning light will flash. The system detects an attempted break-in or theft when any of the following occurs: 1) the vehicle is forcibly entered; 2) the engine hood is forcibly opened; 3) the doors are unlocked without the use of a key; or 4) the cable from the negative (-) battery terminal is disconnected and reconnected.

If the system enters the alarm sounding state, any unlocked doors will automatically lock.

The system has 4 states: disarmed state, arming preparation state, armed and alarm sounding state.
