摘要：
A method for controlling an EGR system includes determining whether diagnosis conditions for an EGR cooler are satisfied while the EGR system operates. The EGR system is turned off when the diagnosis conditions for the EGR cooler are satisfied and a retard amount of ignition timing is larger than a first reference value. The EGR cooler is diagnosed base on a comparison result of the retard amount of the ignition timing and a second reference value while the EGR system is off.
