    Move on to the other codes;).

    B1421 is the least of your worries.

    Based on your previous codes, I’d look at block 10 for data as that could be causing the P0A80:(.

    Good luck and keep us posted (y).

    The photo (showing the connector on the LHS) in your linked thread is correct. Don't really know what the connection to the HV battery is, but apparently fixing that connection by cleaning up the corrosion gets rid of the code.
    No, why would you even think that was a good idea?
    The B1421 is not even a problem unless you are getting it when direct BRIGHT sunlight is hitting the solar sensor (over on the RH side at the back of the dash just behind the windscreen).

    As others have said. focus on the HV battery codes, they are your real issue.
