ECM Inspection Table

WARNING: This page is about a different car, the 2004 Nissan Frontier. However, it is still accessible from the selected car via links, so may be relevant.

Specification data are reference values and are measured between each terminal and engine 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 the ECM terminals, such as the engine ground.

"Star":  Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope).

*:  Any mode except OFF, ambient air temperature is above 25°C (77°F)
