ECM Inspection Table
WARNING: This page is about a different car, the 2004 Infiniti I35. 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 ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring the input/output voltage. Doing so may result in damage to the ECM's transistor. Use ground other than the ECM terminals, such as the ground.
