1. A method for diagnosing an abnormality of a vehicle cooling system using circulation of cooling water stored in a reservoir tank, the method comprising:
generating, by a processor, a diagnostic mode operation command based on state information of a vehicle including a disturbance factor received from a sensor;
determining, by the processor, an RPM of a water pump in response to the diagnostic mode operation command;
determining, by the processor, an abnormal state of the cooling system based on the RPM of the water pump being equal to or greater than a predetermined threshold; and
notifying, by the processor, the abnormal state after determining the abnormal state of the cooling system through a display.
