When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
I
Do not 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 the ECM
terminals, such as the ground.
