I've got a 2012 and CAN'T check the codes. I would think it would be as simple as everyone says it is. I've tried going back and forth really fast, really slow, what I would consider normal, 3 times, 4 times, just back one click, and all the way back to off. NO luck with any attempt. Even tried opening the door after I remove the key to see if there was something with the radio still being on that would affect it between tries.
I had a code just come on today on the way to work and want to check it. I hope it is just something I'm doing wrong. Anyone have any ideas/experience with having trouble reading the codes?
