I am driving imiev MY201, US model.
During the autumn strange things started to happen. I could drive it but after slow charging at home (220V, 16A, or even 6A), I started to get yellow car error symbol and error code P1A15 (high voltage circuit). After clearing the error code and charging the 12V battery, I was able to start and drive it without any problems and even charge at fast-charging stations. But now in winter, after staying at home for several days or even week, I started to get this error code after each charging. And finally, I am not able to start the car at all.
Now, after I delete the error code and start the car again, I get a red battery warning light and the car does not start. After few attempts, I get again yellow car error light and P1A15 error code. Even if I clear the error code and try to charge, I get at once yellow car error light and P1A15 error code.
I measured a 12V battery (purchased 11.04.2018). When it is off, I get 12.46V. When I turn the key to the on position without load, I get 11.94V.
On this forum, I found some directions on how to measure EV-ECU (under the rear seat) but not sure if I measured the right module. The Key was in the ON position.
I included some photos that you could guide if i am wrong.https://ibb.co/pLQxKnkhttps://ibb.co/ZNgS10Khttps://ibb.co/9tpTZX5https://ibb.co/hL1sMs7
Where I should look for the problem?
