Well the repair worked! I preheated the heat sink and chip with a heat gun before soldering. It would be nice to find replacement LED chips in case it is more than just the leads, but I suspect that most of the failures are the same problem. It seems like a very weak part of the design. I will...

I just had my low beam go out on my 2012 Leaf, and refuse to pay for a new unit. It is not too hard to get into. There are a handfull of screws, some plastic tabs, and a very sticky sealant holding the two halves of the unit together. Once inside, it is easy to get to the two LED chips. On mine...

I think we have a resolution! The original BCM was still working after a day of driving aorund, so I decided to button everything up. Once I got the switches plugged back in on the panel under the steering wheel, the symptoms came right back. Process of elimination narrowed it down to the...

One more update for tonight. I left the new BCM mounted in place, but swapped all the plugs back into the old one so I could close the windows. Miraculously, everything seems to work now! The car starts and drives, and when I turn it off, the current drops to a couple hundred mA within minutes...

Well, there is good news and bad news. The used BCM arrived yesterday. I installed it this evening, and the car seems to go to sleep properly. The current is around 250 mA after a few minutes. The bad news is that I didn't realize that the key is programmed into the BCM, so it doesn't actually...

Two full days of a good battery, and disconnecting every plug in the doors and center console didn't result in any changes. I'm out of ideas at this point (Other than hooking a toggle switch up to the SSOFF relay to easily shut it down). I did purchase a salvage BCM for $75 on ebay. It seems...

I will give it a more thorough attempt. This weekend I will unplug all those switches again, and maybe even the parking brake and gear shift buttons (this was quite a violent rain storm- both seats and center consol were wet) to be sure. Last night I put in a good 40 Ah SLA backup battery that...

By the way, here are the current DTCs read through LeafSpy: C1A62 0108 BRAKE Control Mod Pwr Supply BR-53 B29A0 296C CHARGER N/CHG Port Engage Err VC- 95 B2802 2368 CHARGER Q/CHG Isolation Sig Err VC- 56 B2821 2328 CHARGER 12V Power Supply VC-65 U100A 876C CHARGER B2902 4268 CHARGER OBC Memory...

Well I bench tested the two relays this evening, and both seem completely fine. Another thing I noticed is that when I plug in the bluetooth OBD adapter, LeafSpy is active no matter what the state of the car's ignition is. I guess that makes sense if all the varius ECUs are not shutting off. I...

At this point, I have to pull off the negative terminal if I am parking for more than a few hours, otherwise it will be flat at the end of the work day. I have the factory service manual and have been looking through the wiring diagrams. One relay is the SSOFF (VCM Self Shutoff) relay. Its...

I tried another battery that I know is good, but still the same results. I made sure it was topped off with a separate charger first before installing it. After about 15 mintes with the car off and without disturbing any doors/windows, it was reading a voltage of 12.5 and a current draw of 2.24...

I guess I am not sure. It holds its voltage well overnight after charging and dissconnecting it from the car, but I'm sure it will be shot after this treatment even if it is not already. If the battery is no good, what would cause the car to draw current from it when it is turned off? If some of...

Hi Everyone, I have thoroughly enjoyed my 2012 leaf for the past 6 months. I was just thinking how little work I have had to do on it, when an unpredicted isolated thunderstorm dumped 1/2" of rain through the open front windows. When I got home, I turned it on and rolled up the windows with no...
