ECM Terminal and Reference Value

ECM Terminal and Reference Value

Preparation

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 ECM's transistor. Use a ground other than ECM terminals, such as the ground.

































































: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

*: Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to [How to Handle Battery] How to Handle Battery.
