U6 is eeprom.

Any bios chip reader should be able to read it.
I used CH341A programer to read it, but there are a lot of different devices which could read this chip.

Here is picture inverter main board. I read eeprom chip from board and i can see vin number inside. So it should be CRC inside eeprom, right? Does anyone has access to same chip? I need several dumps from different cars to find out CRC and how it calculates. https://forums.drom.ru/attachment.php?att...

I tried, but my Chinese scanner was not able to do it.

I installed used MCU. Unfortunately it has VIN inside from car from which it was taken and so far I didn't find way how exchange this VIN to mine. So I have error P1B2D VIN mismatch right now. I want to go to dealer and ask if they can fix this problem. I tried to put MCU's VIN to EVECU and P1B2D di...

Yes, I can ask. I don't think if it help, but I will try. Thank you for you help!

Dealer did procedure for P1A15 and told that problem should be in inverter which cost $8k new.

I decided to go to dealer again. They asked $118 per hour only for diagnostic and they expect 3-6 hours for diagnostic or may be even more

today I checked by scope signals from ev-ecu to main(+), main(-) and precharge contactors. I was able to see main(-) and precharge signals, but not main(+). Then I tried to manually engage main(+) contactor and I hear clamping noise from battery. Then I tried to manually engage main(-) and precharge...

Lets continue in fresh topic which I opened about my problem.

I used diagnostic software and made video of what is going on after turning key to ready position. I left link for video here earlier. Ok, that would do it! Sorry, I somehow missed the video links earlier. It seemed to get to 338 V, which is only 12 V short of the battery voltage of 350 V, and is 9...
