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.

TERMINALS VOLTAGE REFERENCE

TERMINAL NO.	WIRE COLOR	ITEM	CONDITION	DATA (DC Voltage)
84	PU	Electrical load signal (Headlamp signal)	[Ignition switch: ON] Lighting switch: 2ND position	BATTERY VOLTAGE (11 -14V)
84	PU	Electrical load signal (Headlamp signal)	[Ignition switch: ON] Lighting switch: OFF	Approximately 0V
96	Y/G	Electrical load signal (Heater fan signal)	[Engine is running] Heater fan switch: ON	Approximately 0V
96	Y/G	Electrical load signal (Heater fan signal)	[Engine is running] Heater fan switch: OFF	Approximately 5V
