ECM EC-489 < ECU DIAGNOSIS > [QR25DE FOR CALIFORNIA] C D E F G H I J K L M A EC N P O TERMINAL LAYOUT PHYSICAL VALUES NOTE: • ECM is located behind the passenger side instrument lower panel. For this inspection, remove passenger side instrument lower panel. • 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 dam- age to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.
