   I have a 1992 S82 hijet and my check engine light stays on. now I don't think I have a computer box to plug into to tell me why it's on. so what would be the reason it could be on?

   Diagnostic codes, maybe 1992 is too old for that, but check/read here https://minitrucktalk.com/threads/diagnostic-connector-location.21031/
