TROUBLE DIAGNOSIS

ECM Terminal and Reference Value


PREPARATION






ECM (1) is located in the engine room left side near battery.

ECM INSPECTION TABLE

Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT.

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.
