Ignition Signal: Wiring Diagram

WARNING: This page is about a different car, the 2006 Nissan Xterra. However, it is still accessible from the selected car via links, so may be relevant.

For PG Power or Section, go to SYSTEM WIRING DIAGRAMS .

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.
