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 ground.

ECM GROUND TERMINALS INPUT/OUTPUT VOLTAGE REFERENCE

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

Specification data are reference values and are measured between each terminal and ground. Pulse signal is measured by CONSULT-II.

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 ground.
