smog check issues

[2020at4nv]

Had my 2020 at4 2500 diesel smog checked it passed. While paying for it , the guy said something about dash warning lights, but just drive it and they'll go out. Here's what is on the dash: Brake, abs traction control and check eng light. I've had two chevy 2500 diesels (2007,2010) and this never happened with them. Is this normal?

also DIC messages of: service trailer brake sys service PS, Service ESC, ABS and traction control lights on. These all happened while smog check. I erased both codes , everything good now. Was just wondering if this was normal when getting it smog checked
