When we try to monitor communication between the EMU Black and TCU it does not talk to each other. If i sniff the CAN, i see only data going from EMU Black on adresses 0x600-0x607 but no communication from TCU.
Please tell me how we can fix it.

Maybe TCU is setup to read only? I've got like that, to not throwing fault code about "incorrect variant coding"

Hello. In the picture you can see that you have set "CAN SPEED" to value 4. value 4 means communication 1mbps. for sure this is the communication speed you have set in EMU black? If you have a BMW e46 as in your nickname, if you use serial dash on the CAN bus, you should have 500kbps communication.
