Perhaps a simple ohmmeter test from the vehicle's 1772 connector? It should read quite differently if the leads are reversed to swap the polarity and the diode is good. I'll try it on mine the first chance I get.

It's asking a bit much to have owners swap cars and EVSEs around as things go forward. Hopefully, a test for this becomes part of their standard diagnostic equipment.fotajoye said:...if some EVSEs check for +/- 12v and others don't and it only shows up on some EVSEs when the diode is shorted, it could mean that is a weak part in the Leaf and will not show up in their QA processes...
