Check engine light trac light and VSC lights will come on

Question

My engine light will come on first then a few seconds later the trac off and vcs lights come on. My mechanic has run the DTC and did a smoke test with results being okay. The lights don't stay on. They will come on, for a day to a week then off again for a day to a week. I think there is a loose connection somewhere but HELP!!
