Sorry. I'm using dealerships near Hagerstown and Frederick MD. (I'll update my profile.)

I'd like to learn a bit about this, thanks.

Darell explained this in his thread, but IIRC ...

a diode is often used as a one way valve for electricity, in the same way that valves exist for water that only let it flow in one direction. The presumption here is that the diode failed in the open position so that when the EVSE checks for the diode it finds current flow in the prohibited direction. Insertion of a new diode anywhere along the path of that circuit renews the one way valve.

Incidentally, this is why diodes have orientation ;-)

Just duplicate information. But hey, it's much more useful to have two CORRECT answers than ZERO correct answers from Nissan.

IF you had read my post and understood it, you would grasp why the old diode can stay in place and why an unusual fail whereby the old diode is in the off position cannot be repaired with a new diode nearby.

But hey, don't read the above either. It is for others with a bit more curiosity.
