Method for diagnosing failure of and providing maintenance information about ATM

A method of providing failure diagnosis results and repair information to a maintenance worker in a site when a failure of a banking automated teller machine (ATM) occurs, the method comprising:

• generating a failure code by identifying a failure-occurred module in which a failure occurred in a banking ATM;
• checking sensor values measured by multiple detection sensors provided at respective nodes on a return route of a failure-occurred medium in a financial transaction process in which a corresponding failure occurred;
• reading sensor information of a node at which an abnormal sensor value that falls outside a preset normal range was first sensed, among the checked sensor values, when the abnormal sensor value is detected;
• generating failure information comprising the failure code and the sensor information of the node at which the abnormal sensor value was first sensed;
• and
• providing the generated failure information to a maintenance worker.
