Zusammenfassung:	PROBLEM TO BE SOLVED: To detect abnormality in a plurality of electrical equipment (electric load) by a single detector. SOLUTION: An electric load abnormality detecting device for a vehicle is provided with a heater resistor 24 serving as a resistance component of an electric heating catalyst and a common current sensor 25 detecting each load current in a motor 27 of an air pump. In an ECU5, a plurality of electric loads are operated with timing made different, and abnormality of each electric load is detected in accordance with a current value detected by the current sensor 25.
