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.

INPUT/OUTPUT VOLTAGE

TERMINAL NO.	WIRE COLOR	ITEM	CONDITION	DATA (DC Voltage)
29	PU	VIAS control solenoid valve	[Engine is running] Selector lever: P or N	0 - 1.0V
			[Engine is running] Selector lever: D Engine speed: Below 5,000 rpm	BATTERY VOLTAGE (11 - 14V)
			[Engine is running] Engine speed: Above 5,000 rpm	0 - 1.0V
111	W/B	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/B	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 R	Power supply for ECM	[Ignition switch: ON]	BATTERY VOLTAGE (11 - 14V)
