There are fuses on both the AC input and the DC output side which can be checked once you get to the chargger.
We have seen failures of the AC input side: EMI filter capacitors, the turn-on relay and it's drive circuit, and the precharge resistors that bypass the relay. On the HV DC output side: current sense circuitry, HV snubber caps, and output fuse.
i'm assuming that you were using a strong and good 12V aux battery. A weak, old or worn out aux will cause numerous problems including preventing charrging.

The battery has a 10/19 date sticker on it and it looks new. I have four days of working until my next run of days off, so I can try some more of the little things.
Forgot to include that the car does charge normally when using the HVDC charger.
UPDATE: I did the code clear, disconnected the 12v battery for 24 hours (day job), and put it on a trickle charger. I hooked everything back up, and still the same result, and same codes. I guess I'm looking at exploratory surgery? Can this be opened up from the top without draining the coolant for the initial inspection for any "smoking gun" causes?

i took the car to a Nissan dealer and they stated that there wasn't any fault codes and that the onboard charger had to be replaced (3500 euros).
thanks in advance

According to this page (4th last entry), it may be this 200V 1.1A fast silicon diode:nlspace said:2. The diode in the yellow box area is marked "2U" and i can't find a datasheet for it; it is SMA sized.
Maybe this one, which is Schottky 40V and does have marking code S4, but a different manufacturer [ edit: and different layout of digits ] :nlspace said:3. There is another similar SMA diode marked "S4"--maybe Schottky 40V?
