Abstract
An electrical load abnormality-detecting system for an automotive vehicle detects abnormality of each of a plurality of electrical load devices installed on the vehicle. A current sensor is provided commonly for the plurality of electrical load devices, for detecting a total load current flowing through the plurality of electrical load devices. The plurality of electrical load devices are separately put into operation, and abnormality of each of the plurality of electrical load devices is determined based on the total load current detected by the current sensor.
