I guess what I'm looking for is: Have you experienced and DTC's while using the EVSE?
The current L2 I have, came with the car when I bought it used, and does charge the car just fine.
However it fails in some aspects, it will set a DTC if allowed to be shut down by the cars timer, and will not start charging if plugged into the car, and the "overide timer" button is pushed. This leaves me to believe that something is still "hot" when the EVSE is shut off. Like not the power circuit but more likely the proximity or control (current setting) remains active.
Since the DTC goes in-active if the car is shut down then re-started, it has never been a problem, but does indicate something is not right with that EVSE.
I'm fairly sure it isn't a fault within the EVSE but that the EVSE wasn't designed to correctly meet the J1772 protocol.
Before I lay out coin for another, I want to be sure it does meet the requirement of the protocol
