Default Trouble reading codes.

Ok i think im doing something wrong...i tried to flash the codes on my 93 z....but i cant seem to find what they are...i jumped the terminals...the ses light came on...once paused....then two flashes...pause...and did this a total of three times....then ses light flashed 8 times...long pause....twice flashes...short pause... 8 flashes....long pause...2 flashes...short pause...8 flashes....short pause...3 flashes...long pause...2 flashes...and this repeated three times...intill...i got....1 flash...long pause...2 flashes....which i take it its code 12....ok what codes do i have...or did i not even make sense...sorry for the tricky question.

It will flash 12 at the very beginning and at the end. I believe that is just telling you that it is in "code reading mode". It will flash each individual code 3 times. 82 is your first code. If everything is right, 32 is your second code but when I run mine, they always come up in numerical order.

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.
