Abstract
In a load controlling apparatus used in, for instance, an automobile, equipped with a mulfunction diagnostic circuit, there are employed: PA1 a power source V; PA1 a load 1 operated by power supplied from the power source V; PA1 a drive 3 for controlling supply of the power to the load 1; PA1 a control 4 for supplying a control signal "a" to the drive 3; PA1 a first and second detector 2, b for detecting the current flowing condition "b" to the load 1 based upon the control signal "a" derived from the control 4, and also the voltage condition "C" applied to the load 1; PA1 a judging device 11 to 18 for judging an extraordinary condition of the load 1 and the drive 3 based upon the signals from the first and second detector 2, b, and the control signal "a"; and, PA1 a display outputting a signal "d" representative of the respective extraordinary condition of the load 1 and the drive 3 based upon the judgement result obtained from the judging device 11 to 18.
