Looking for advice if I should try the diode fix or just replace the OBC for my 2012 Leaf.
A couple of days ago, I noticed my breaker for my dryer tripped (I have an auto splitter for 220V charging). I didn’t anything of it, until I noticed the next morning that my Leaf didn’t charge. At 80% charge its range is down to ~35 miles, so it is kind of critical it charges every night. Plugged in the 220V charger, got one beep that it was connected, but didn’t get the double beep that it was charging. Tried my 110V charger: same thing so the charger isn’t the issue.
After reading lots of posts and watching EV Enhanced’s Video (), measured 4.5 Volts across the proximity port, but got infinite resistance both directions across the pilot port (i.e., no reading). I ran a code scanner for the onboard computer and nothing. I drove down the street to a local CHAdeMO charging station, and it charged fine.
I figured unplugging the 12V Battery for a few hours to reset the whole system couldn’t hurt. However, now when I plug in the 110V or 220V chargers, I get the one connection beep, the double beep for charging, but then a click 2-3 seconds later, and charging stops. Also, I am getting no voltage across the proximity port and still getting no resistance reading either direction of the pilot port. Still no computer fault codes.
Despite its minimal range, I love my Leaf (my wife and I can switch cars when we need to drive further). Curious thoughts on if the diode fix would be worth a try given this situation, or if I just need to suck it up and replace the OBC, or any other ideas. I am just not getting the same readings across the pilot and proximity ports or I would just go with all the other advice in these forums.
Thanks!
