CONSULT-II Reference Value in Data Monitor ModeEBS00BA8
Specification data are reference values.
ECM Terminals and Reference ValueEBS00BA9
Specification data are reference values and are measured between each terminal and body ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
