error 4680 49a6 e71 n57

hello everyone.
I have these errors:
4680 input voltage 2
49a6 LIN bus: communication error.

Error 49a6 takes a while, I know it's the heater relay, but since I live in a warm area it doesn't bother me much.

Error 4680 has appeared again.
The car is traveling on the road and wants to stop
Do you think they may be related?
