Ouille, mon ECU !
 

• 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.

Trouvé dans Workshop Manual de Navara D40, j'ai trouvé l'image sympa.

Et juste à coté y a écrit :
• Do not use ECM ground terminals when measuring input/out-
put voltage. Doing so may result in damage to the ECM's tran-
sistor. Use a ground other than ECM terminals, such as the
ground.

Faut le savoir de pas utiliser la masse de l'ECM comme masse ...
(Merci Mr Nissan de nous le dire)

EDIT : d'autres
Be careful not to jar components such as ECM and mass air flow
sensor.
