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, and the hazard warning lights 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.
