ECM Terminal and Reference Value INFOID:0000000004499945
PREPARATION 1. ECM (1) is located in the engine room left side near battery. • : Vehicle front
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 wh en measuring input/output voltage. Doing so may result in dam-
age to the ECMs transistor. Use a ground ot her than ECM terminals, such as the ground. PBIA9221J
