A malfunction of an on-board diagnostic (OBD) controller system is diagnosed by comparing a voltage of an input part of an OBD controller with a voltage of a battery. The OBD controller is connected to the battery through a communication line in the HEV. When an input voltage measuring circuit or the controller is malfunctioning, the malfunction is diagnosed.
