good day goodfolks.
so todays attemt was as following
i measured the AUX 12V battery to 11,05V. so this i belive is on its way out. for fault finding purposes i connected my 12V dummy charger on the battery. this held the voltage to about 13,5V all day. i use this chargen when coding old BMWs.
so after charging the car for about 10 minutes, i switch the ignition to on, cleared all fault codes and tried charging whit the charger connected.
after clearing codes i have following codes stored.
-U1111 display CAN timeout
-P1A08 inhibitor SW 
-B1702 transponder read error. the key for the car is completly FUBAR so have orderd replacment housing. dont think this is relevant for charging.
*ignition off, plug in charger*
*fans start, runs for about 5 sec. relays clicking so on so fort.*
*fans stops, granny charger light turns off*
codes after charging attemt:
-U1111 display CAN timeout
-P1A08 inhibitor SW
-p1A12 OBC abnormal stop
so after this i tried diffrent random stuff just to see what would happend.
first i opened the OBC to messure voltages.
during charging i have:
-230V in on the black and white wire going to the PCB card in bottom
-330V DC on the pink and blue cable, and both orange cables. so guess these are connected somehow
i then for funnsies, disconnected the big DC cable that i presume is from the main battery.
connected the carger, 230V in, 0V on DC side. (pink and blue, and bot orange cables)
fans only runs for about 1-2 sec, before stopping. so i guess if fuse to battery or something like this the fans runs for a shorter time, nice to know.
i then disconnected the CANBUS cable on the top board and connected the grannycharger, granny charger does not light the "charging" lamp. but if you turn the ignition ON it will turn on the "charging" light on the granny charger and this will stay on untill you disconnect the cable.
so after all this i deleted all fault codes stored and tried one more time to charge, no dice.
before
U1113 MiEV remote CAN timeout
P1A08 inhibitor SW
after:
U1113 MiEV remote CAN timeout
P1A08 inhibitor SW
P1A12 OBC abnormal stop.
i the removed the top board and checked the connections from the filter fransformers to the bottom board. and found that the cable marked B2-T8A and one to the DC filter(the one in the right corner whitout a name) side was swapped. if the picture from virusman is correct though
so after swapping these, i tried to charge again and got a new code.
U111D OBC CAN- timeout
U113 Miev remote...
P1A08 inhibit SW
i then remebered someone talking about a fuse on the top board F701, so i checked this and found it to be blown.
so now i have taken the top card whit me back home to see if i can resolder something to test.
can F701 create a U111D OBC can timeout fault that leads to a no charging fault?
my scan tool does not have "the archive for OBC module" so cant take out OBC spesific codes.
behold, the magnifisent beast
charging setup, fluke to messure voltage drop.
two diffrent grannychargers, both know to be working (whit a toyota prius...)
