Went to drive my 2011 Leaf to work and noticed a weird smell in the cabin. Tried driving it but the EV warning light was on and it was in limp mode. Opened Leaf Spy and it showed 67% charged instead of the 80% it should have been. Checked the EVSE and it had no power due to the RCBO (residual current protection and over-current circuit breaker combination) for the charger circuit being tripped. Tried to reset it and the power came on but no luck getting the car to charge. Pulled the DTCs with Leaf Spy and found the following:
P3196 00C0 - EV/HEV CAN Error EVC-274
U1000 00C0 - EV/HEV CAN Comm Circuit
U1000 000E - HV Battery CAN Comm Circuit
P3196 000E - HV Battery CAN Error EVB-99
Took a look at the service manual and it basically says 'replace on-board charger'. Given the particularly epic smell of burning, I pulled the charger out after work and it's absolutely toast. The big electrolytic cap in the box had vented, a film cap had completely melted/burned up and there was black soot all over the bottom of the control board.
So, I'm in the process of trying to source a replacement on-board charger (part numer 296A0-3NA3A). Current situation is that there is only one that I've found available from a wrecked 2011 about an hour away for NZ$1600+GST which is about US$1300. Alternatively, I can see a couple of ebay or a couple of other online auto-parts stores with slightly different part numbers (-3NA2A or -3NA8A) for around the US$1000-1200 mark new. For reference, a 2nd hand
I saw another thread discussing the Brusa charger upgrade option and mentioning that the OBC units could be had from wreckers for a few hundred US$ which would be brilliant, assuming I could find one and get it shipped somehow.
Just wondering if anyone has any suggestions or knows of a 2011 Leaf being parted out anywhere?
For reference (in case anyone is interested) the car is a Japanese import currently living in Auckland, New Zealand. It has 52,000km (about 30,000 miles) on the clock and was imported a year ago at 39,000 kms. SOH was about 82% when I imported it and was about 78% on last check a few weeks ago. Never quick charged while I've had it, always charged using the supplied Nissan EVSE at home from a 240V/16A socket or very occasionally a ChargeAmps Spark cable to charge off a 240V/10A socket at work.
