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.

Terminal No.	Wire color	Item	Condition	Data (DC voltage)
23	B/O	Fuel pump relay	[Ignition switch: ON] For 1 second after turning ignition switch ON [Engine is running]	0 - 1.0 V
23	B/O	Fuel pump relay	[Ignition switch: ON] More than 1 second after turning ignition switch ON	Battery voltage (11 - 14 V)
