Without knowing what the computer is seeing it's all a guess. The petal dance takes time to get right unless the petal is bad and then it would never work this sounds funny but l will try to help you to go through the petal first turn the key on then count in your head 1 Mississippi 2 Mississippi 3 Mississippi after the last Mississippi push the petal down 5times within 5seconds make sure the last time you are in the up position take your foot off the petal and count 7seconds just like you did in the beginning than hold the petal down until it blinks and start counting it should start after Ten seconds of it does not work turn key off and start over it takes practice also if you get it if it blinks ten times in a row that counts as a zero all the codes are four digits at end of the codes it will blink ten in a row three times if there are no codes try again and get back to me good luck
