ECM Harness Connector Terminal Layout






ECM Terminal and Reference Value

PREPARATION




ECM 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: Do not 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.
