ECM Terminal and Reference Value

TROUBLE DIAGNOSIS


ECM Terminal and Reference Value


PREPARATION
1. ECM (1) is located behind the passenger side instrument lower panel. For this inspection, remove passenger side instrument lower panel.





ECM INSPECTION TABLE
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-III.

CAUTION:
Never use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.
