Hi guys, a little help here? :shock:
I have troubles fixing my aging, but until recently, almost perfect "Zerina", a 2012 C-Zero, 16 kwh battery pack replaced under warranty in 2017 (last time I checked SOC was at 93%, I could still easily drive for 120 / 130 kms).
Zerina has started having trubles last spring. It would suddenly shut off while driving, on the dashboard: car! + battery lights would come on and "ready" would come off. I took it to the nearest Citroen dealer, they added a couple mass wires and oddly enough (for me), Zerina seemed to have come back to life. I was quite optimistic but at the begginig of summer, after one night charging (@ 3kw AC) I noticed the battery was not completely full, it was more or less at 80%. From that day on every time it would charge less, until some weeks later it would only start the process, fan would start as usual, but after some seconds the charger would quit. I could charge on Chademo though, so I supposed there was something faulty on the On Board Charger. At the same time Zerina has started to show also the old symptoms, it would shut off while driving, and that too seemed to be more and more frequent. I took it again to the shop, after a quick check sure enough the dealer told me the OBC was faulty and needed a replacement. I wasn't expecting the price tag though: 7000€ + fees, probably more than the residual value of my car, so I started searching for a 2nd hand part, which I found some weeks ago. It came from a totalled car, (just to be sure I took all the electronic boards as spare). The car was a 2013 model, I didn't know Mitsubishi had changed the design of the OBC and MCU, but with the help of this forum and the videos of Peter K, I was able to adapt the new OBC and install it. I finished this morning but now the charging light on the EVSE never comes on, the fan would cicle as usual (so I know the 220v comes in), but no charging, not just this, but on the dashboard the battery charge indicator show no bars, the diagnostic tool show a single error message: no communication with MCU. now I am wondering, is the OBC VIN coded so maybe it doesn't pass the signal?
Tomorrow I'll try and open the MCU to test the 450V 20A fuse, anyway if it is blown it means there are some problems with those boards. So second question: is it possible to swap a 2012 MCU with a 2013 model (which I have here at home), like I did for the OBC? the sockets are different, it seems on the 2013 model there are more pins on them, I am not sure if this could be done, but even if this was the case, is the MCU VIN coded / locked? I am at odds, with my little car standing dead since july, any help greately appreciated!
cheers
