12. A method for diagnosing a malfunction of a system having a radiator provided with an air purifier;
- an OBD sensor provided to a coolant tank which makes up a bottom portion of the radiator, having a communication chip and a thermocouple; and
an electronic control unit (ECU) connected electrically with the OBD sensor in order to determine whether the OBD sensor is fixed to the coolant tank, comprising;
outputting a diagnosing signal from the ECU in an early state of an engine operation; and
determining that the air purifier normally operates, if the outputted signal is returned to the ECU via the communication chip. - View Dependent Claims (13, 14, 15)
