Today my ABS light came on so I jumped the connection to check the code. While I was doing this, I saw that I had 3 codes...72, 74, and 71 in that order. What is weird is that prior to me jumping it, I did not have a CEL. I drove all the way to work (about 30 minutes) with a CEL, I still have no CEL but if I jump it i get these codes everyime. What does this mean??? Is it maybe the last codes that I had and we never checked, like maybe the codes are just stored for reference or is it something I should still address. I do know that it is random misfire...
