You need to leave the keys in the ignition with the stereo on displaying the error sign for about two hours. Then the four/ 6 dashes with come back and you can renter the code. You have entered the code incorrectly 9 times so it needs to be left for a long time. I had error 5 and it took an hour. Good luck. Not sure how to find the code tho... good luck
