PURPOSE: A method and a device of alarming abnormality of an air spring are provided to recognize abnormality of the air spring with an alarming part. CONSTITUTION: A key of a vehicle is turned on(S30). A flow meter and an electronic control unit are operated. Air is supplied from an air tank to the air spring. The flow meter confirms volume of air continuously(S32). Pneumatic pressure of the air spring is lowered when the air spring is abnormal. Therein, the vehicle is inclined toward a wheel. Volume of air through the flow meter is increased. Volume of air is supplied to the electronic control unit. The electronic control unit compares volume of air and set value(S34). The electronic control unit transmits a signal to a warning part when volume of air is over set value. The warning part transmits abnormality of the air spring to a driver(S36). The driver takes necessary actions(S38). Thereby, accident by the air spring is prevented.
