A multifunction vehicle security system, which includes a receiver connected to a control unit which processes received information and enables various functions. The user can increase or decrease the sensitivity of the system sensor, by merely pressing a button on the remote control to increase the sensor sensitivity, and another button to decrease the sensitivity. A special programming mode resets the system programmable features and values to factory settings, to quickly re-establish to a known state all or only preselected features. The system provides automatic silencing during night conditions of the system's arming/disarming chirping to confirm the change of system state. The security system generates a door unlocking command to the vehicle's power door locking system to unlock the doors in the event of a vehicle collision. A theft warning LED energy management system conserves battery power when the vehicle is left unattended for long periods of time. When the system is armed, a timer is started, and upon expiration of a time period, the LED activation duty cycle will be reduced from an initial duty cycle. The polarity of the door locking and unlocking signals is programmable, enabling the installer to match the polarity requirements of a particular vehicle. An enhanced panic mode is provided, wherein the vehicle doors are automatically unlocked if the vehicle ignition switch is off, or if the vehicle ignition switch is on, the doors will be automatically locked. The system provides installer programmability of the normally open/closed mode for the vehicle starter, ignition, and/or fuel pump disable relays.
