CAN bus in infiniti qx
recently I got air bag light blinking, radio not working (no volume change from 0) and a few more errors about around view camera U1300 and can bus problem U1000.
I checked all fuses, grounds, and start to play with can bus signals.
I always beveled that idle voltage for can H and L must be close to 2,5V but
On ACC  this level is around 2V (H and L) but on ignition voltage jump to 2,5V like use to be. I didnt decoded those because looks bad.
Tried to trace module by module but no luck, resistance is ok
May someone of you have any idea or seen something similar?
Thank you for help
