Abstract
A vehicle includes an electronic control unit. The electronic control unit is configured to detect a first current value in a period in which a current path is switched to a non-conductive state by an ignition-off operation. The electronic control unit is configured to detect a second current value in a period that is after an ignition-on operation is performed and before the current path is switched from the non-conductive state to a conductive state in the case where the first current value falls out of a specified reference range. The electronic control unit is configured to diagnose that there is an abnormality of the current sensor when the second current value falls out of the reference range and to diagnose that there is no abnormality of the current sensor when the second current value falls within the reference range.
