I’m working on a 311. Will not take car calls from car panel and will not take car calls thru OCSS. How do I troubleshoot the car serial link communications? Can I disconnect RS boards to find bad one or just start replacing them?

I got it figured out. The car calls had been accidentally turned off in OCSS!
