Diagonistic Port Not Workin?
Hey everyone, I now have been workinf at Advance Auto as my new job. Well we do free diagonistic checks & the other day I went out to do some lady's car, found her code & told her I was done & what not. So then I figured I'd go & see why my check engine light was on. Well I plugged it in & nothing came up, the code scanner wouldn't even turn on.
Would anyone know why it's doing this & if there's anyway to correct it?
