If you mean the MIL, then I am also having the same issue. It came on a couple weeks ago, and I took it in. They said it was a stored code.....not active, and they cleared it. I knew it would come back on eventually, so I am off tomorrow to have it checked again. They never told me what code it was actually showing the first time. I hate this ****.
