Message ECU, or injector driver transistor, or coil pack driver transistor, etc, is simply to use a 12V LED and attach it into the harness side connector with the engine running to verify you are getting a signal to the component in question.

Keep in mind that LEDs are polarity sensitive so if you dont get a pulse, swap its leads around to double check.
