Trouble reading codes.
Run them again. It will flash "SES, pause, SES SES, long pause" 3 times and then it will give you your codes. For instance, if the SES light flashes 3 times, pauses and flahses 4 more times three times consecutivly, your code is 34. Am I making sense? When it is done giving you all your codes, it will give you your 12 code again and thats how you know your done. Good luck with it.
