ECM Terminal and Reference Value
ECM Terminal and Reference ValuePREPARATION
ECM located in the engine room passenger side behind reservoir tank.
ECM INSPECTION TABLE
Specification data are reference values and are measured between each terminal and ground. Pulse signal is measured by SDT.
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.
