Took the truck to dealer to diagnose a message the parking brake not working. Said my wiring to HCU (ABS) was corroded. Picked it up as they said it would cost $2300 to fix. Asked what parts they were replacing and he didn't have the list. Said they hoped it would fix the problem. Not very confident in them. Anyone else have this problem?

Talked to service advisor and he found the part they were going to replace. It was the wiring harness that they were going to replace. Mechanic hoped that would clear it up but was not sure.

Can wiring aka Controller Area Network and corrosion is a nightmare. Your working with low voltage. It seems like a logical place to start. Probably after that your looking at modules and tracing other possible issues.
