ABSTRACT:
An auxiliary circuit continuously executes a timer counting operation under a condition that electric power is directly supplied from a vehicle battery to the auxiliary circuit. A main circuit receives no electric power during a waiting condition and hence minimizes current consumption. Only when a predetermined timer activation time is counted by the auxiliary circuit or an ignition key switch is turned on, electric power is supplied to the main circuit for allowing the main circuit to execute a zero point correction for load sensors.
