Abstract
A first ECU (control device) controls power supplied through a power supply switch, by turning the power supply switch on or off. A second ECU (switching device) turns a power switch on or off. In the first ECU, a processing unit executes non-power supply control processing different from processing relating to control of power supplied through the power supply switch. After a current conduction fault in which a current flows through the power supply switch despite an instruction being given to turn off the power supply switch is detected, the second ECU alternately turns the power switch on and off repeatedly.
