EC-MAIN-01:

Main Power Supply and Ground Circuit

ECM Terminals And Reference Value:

ECM TERMINALS AND REFERENCE VALUE
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 the ECM terminals, such as the ground.
