What's the history of the car? Is it new to you? Has it been worked on before this issue appeared?
You're looking for broken wires or connectors. Sometimes rodents eat through wiring if the car sits outside. See if you can find damage. If not that then you can try going to each connector (ECU, ABS, cluster, etc) and check the CANBUS pins for continuity between connectors according to the wiring diagram which you can google.
