DTC Information And Inspection: DTC Detecting Condition

Item		Detecting Condition	Possible Cause
DTC Strategy	Case1	ECM internal monitoring (knock acquisition check)	Poor connector connection Poor power supply Faulty ECM
	Case2	ECM internal monitoring (atmospheric pressure sensor-related failure)
	Case3	ECM internal monitoring (internal ATIC communication failure)
	Case4	ECM internal monitoring (EWGA overheating defect)
Enable Condition	Case1	Ignition "ON" Engine speed more than 32 RPM
Enable Condition	Case2, 3, 4	Ignition "ON"
Threshold Value	Case1	When abnormality is detected during knock sensor signal suitability judgment (ECU self diagnosis)
	Case2	When an abnormality is detected during ECU self-diagnosis (hardware circuit, sensor memory check)
	Case3	When ATIC communication error (ECU self-diagnosis) is detected
	Case4	When the temperature of higher than 200°C is measured during diagnosis of ECU power
Diagnostic Time	Case1	1.5 seconds
	Case2	3 seconds
	Case3	1 second
	Case4	0.3 seconds
MIL ON Condition		2 driving cycles
