Resolved! - Leaf refuses to "start" after winter storage.

[NoahJ]

I had stored my leaf over the winter when the snow got super deep and I could no longer drive it. I left it plugged into the charger to hopefully keep things form going dead. When I was able to get to it yesterday the 12V battery was dead. I put that on a charger overnight and when I tried today the displays all come on but the vehicle will not start. I get a single chime and then it says to push the brake and the start button. I have done this multiple times with the result being a single chime every time. Has anyone seen this before? I have also included a picture of the Dash so you can see what I am seeing. Thanks for any suggestions or help you can provide.

I would suggest you dis connect the 12 volt, make sure it can hold a charge, then re connect it. Dis connect the charging cable before you pull the 12 volt.
If the 12 volt show good, re connect to the car
Try re connecting the charging cable to the car.
It looks like the Battery management is In-op, no battery temp readings, no SOC readings.
Hopefully it will come back to life, if not you'll need the DTC's and have to follow those procedures

Will try the disconnect. In the meantime I have gotten the DTC while waiting for an answer. 2 readings, one before clearing and one after. Have not disconnected the battery yet...

Thank you! After Disconnecting and reconnecting the battery it all came back to life. I appreciate your help here.

Great news, I was looking over the service manual for those DTC's and it wasn't looking good.
Get a good charge on the traction battery and take er for a run, make sure everything works!
