ABS issue 2008 ProStar

[Waterloo]

Took the truck to the dealer, checked wheels, all is tight. But, we kept getting a datalink non communication code. I'm taking the truck back up in an hour when their electrical tech comes in. The mechanic that checked the ABS system, my engine rebuilder, wants him to look at it. He went as far as he could, not his forte, so I am heading back up in a bit. He thinks it is a bad wire in the harness, any thoughts? All of the sensors came back as working properly.
