My 2012 LEAF has the same issue, leading to a bad OBC diagnosis. I want to replace the OBC myself and am in need of an OBC replacement guide or tutorial. Does anyone have a suggestion?
Get the Leaf Service Manual. It has detailed steps on replacing the OBC. It's not easy, but not the hardest thing ever. If you just have a failed diode with infinite resistance, you can charge with the L1 OEM charger. In that case, I'd recommend wiring a diode in the charging port as a workaround. That's far easier than disassembling the OBC. And if you have a GE wattstation EVSE, throw it away.
In 2011/2012, the OBC is located under the rear seat, so you have to remove the rear seat, and it has coolant lines you have to detach and reconnect.
