Abstract
In a self-diagnostic processing performed by a CPU, whether a vehicle is in an idle stop state is determined based on obtained vehicle operation information and engine operation information in order to perform abnormality detection processing. When an engine has stopped in a vehicle equipped with an idle stop function, electric power is supplied to electrical components of the vehicle, which means a battery supplies currents to the electrical components. Consequently, if a current measurement result obtained by measuring a current while the vehicle is stationary and an ignition is ON indicates that the measurement value is equal to or below a prescribed current value, the CPU determines that an abnormality has occurred in a measuring system.
