Tamás,<br>
<br>
first of all, are you sure these errors are new? Check your log
archive for the error pattern. An occasional "stuck bus-off error
state" is normal for many vehicles, when the car is off.<br>
<br>
The 12V battery may just coincidentally happen to fail right now.
How old is it? If it's relatively new and/or the errors didn't occur
before, it could be an issue with the OBD connection.<br>
<br>

battery drain is continue. In the picture can see, 15:15 set
vehucle module to none, auto update is run at ~3:02 (vehicle
module to hyundaivfl) and i woke up at ~5:20 and set the
vehicle module to none</div>
