Specification data are reference values and are measured between each terminal and ground.

CAUTION: Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals, such as the engine ground.

SPECIFICATION DATA AND REFERENCE VALUES

TERMINAL NO.	WIRE COLOR	ITEM	CONDITION	DATA (DC Voltage)
111	W	ECM relay (Self shut-off)	[Engine is running] [Ignition switch: OFF] For a few seconds after turning ignition switch OFF	0 - 1.5V
111	W	ECM relay (Self shut-off)	[Ignition switch: OFF] A few seconds passed after turning ignition switch OFF	BATTERY VOLTAGE (11 - 14V)
119 120	P L	Power supply for ECM	[Ignition switch: ON]	BATTERY VOLTAGE (11 - 14V)
