Abstract
A fault diagnostic device of a vehicle includes a starting circuit which causes a charger mounted on the vehicle to output a charging start signal and thereby activate a control unit for controlling charging of a battery mounted on the vehicle when a charging gun is connected to the charger. The control unit causes the charger to output the charging start signal when the charger is activated in response to turning on of an ignition switch, and has a fault determination function whereby, if the control unit is not input with the charging start signal, it is judged that a disconnection or power-supply short circuit has occurred in a charging start signal circuit of the starting circuit.
