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.
