1. A method for remotely identifying the status of an anti-theft system applicable to a motor vehicle having a telephone system and an anti-theft system, comprising:
- providing the anti-theft system with a controller unit for monitoring a plurality of sensors detecting a plurality of anti-theft conditions of the vehicle;
connecting the controller unit of the anti-theft system to the telephone system and providing the controller unit with means for pre-setting a time for turning on the telephone system to a power-on state and a time period during which the power-on state continues;
initially placing the telephone system in a power-off state when a notifiee for the vehicle leaves the vehicle unattended to be protected by the anti-theft system;
turning on the telephone system with the controller unit to receive an incoming call from a notifiee at a remote location after the pre-set power-on time and during the pre-set time period; and

Abstract
The identification of the status of an anti-theft system is made by using a motor vehicle telephone system and a system for preventing vehicles from thefts. First, a time is set in order to turn the telephone system to the power-on state. A time period for which the power-on state continues is also set. The telephone system is turned on at the pre-set power-on time, and the status of one or more operating modes of the anti-theft system is checked only when an incoming call arrives during the power-on state and when a predetermined ID code has been entered. With this arrangement, identification can be available from a place away from a vehicle to determine whether the vehicle is at the normal state or not. In addition, the telephone system may be set to the power-on state only at the predetermined time only for a pre-determined period of time. This additional feature reduces power consumption of batteries.
