Datalink problems

Hi there, I got datalink and bunch of other messages coming on my dashboard at the same time. I cleaned my batteries and checked all terminals and replaced connectors on batteries and I was good all day driving until I came home and started my truck next morning. Truck started in the morning no issues but I noticed that when I accelerate idle on my cruise control that all those messages came back on. Im not sure if thats just coincidence or it has something to do with it. Did anyone else had same problem like that or do you have clue what could cause this issue to happen ?
