Infotainment Databus in Single Wire Operation

I'm working on a 2013 EOS that had a major water leak. The telephone module was fried and the power wire corroded off so i replace the module and fixed the wire. Now the Can Gateway sets a code-


00469 - Infotainment Databus in Single Wire Operation
011 - Open Circuit
Freeze Frame:
Fault Status: 01101011
Fault Priority: 3
Fault Frequency: 1
Reset counter: 122
Mileage: 79655 km
Time Indication: 0
Date: 2018.11.27

Can anyone help me out with this? Radio/Bluetooth media function doesn't seem to be restricted.

You'll have to do a continuity test on the CAN High and Low wires. I'm not familiar with the physical wiring in the EOS so can't help where to look. You'll have to find a WD from Elsa. But the principle is to test from the Gateway plug to the Infotainment plug.

CAN will work with just one wire. Did you touch any CAN wires during the fix?
