Ok, dont have a scanner but we counted how many times the check engine light flashed and we dont know how to read it.... it flashed 3 long pause 3 long pause 5 long pause 5 long pause 5 long pause. How do we find out what is wrong w our jeep? or did we do the diagnostic test wrong? All the codes we've looked at are 2 digit, how do we come up with that?
