^^^^^ That is bizarre.
I don't think the technician knows what they are talking about.
But don't understand what they "reset".
The LEAF only powers the OBDII device while the LEAF is charging, or ON, or in READY.
I don't think it pulls any power except in those states.
Now they do pull quite a bit of power, seems like some measured something like 125 mA, about five times the LEAFs normal powered OFF draw.
Nissan has decided the LEAF battery failures are normal.
They were asked about the problem at the big Phoenix town hall meeting.
They responded a few days later on MNL that LEAF battery problems were the same or less than other Nissan ICE vehicles.
Since that sorry non answer about the poor LEAF 12V charging approach, I think they have done NOTHING.
LEAF Advisory Board might have more info.
But we never hear anything from LAB anymore.
They seem to be under the cone of silence
