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.

SPECIFICATION DATA AND REFERENCE VALUES FOR TERMINAL

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	0-1.0V
111	BR	ECM relay (Self shut-off)	[Ignition switch: OFF] More than a few seconds 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.
