DTC Detection Logic

WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.

The ECM detected that the power supply was removed before power-down parameters could be saved.

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P060C-00	Internal Control Module Main Processor Performance (Number of ECM resets - data valid but above normal operating range - moderately severe level)	1	Diagnosis condition	Ignition is ON or engine is running
			Signal (terminal)	-
			Threshold	The monitoring microprocessor reset has been commanded 7 times with the ignition input ON
			Diagnosis delay time	Diagnostic runs continuously when the engine is running
		2	Diagnosis condition	Ignition is ON or engine is running
			Signal (terminal)	-
			Threshold	First reported engine speed after ECM initialization > 300 RPM and time since ECM power up is < 2 seconds or engine speed > 50 RPM and ECM reset occurs
			Diagnosis delay time	Diagnostic runs continuously when the engine is running
		3	Diagnosis condition	Ignition is ON or engine is running
			Signal (terminal)	-
			Threshold	The run-time response indicates an incorrect process sequence or the monitor micro new question update is ≤ 40 msec or the instruction path test fails consecutively for ≥ 0.5 seconds, or, the run-time response indicates an incorrect process sequence or the monitor micro new question update is ≤ 40 msec or the instruction path test fails for a cumulatively of time ≥ 4.8 seconds
			Diagnosis delay time	Diagnostic runs continuously when the engine is running
