You need to do better than that. Your light will blink once hesitate then blink twice this is a code 12 it will do it 3 times. this means it is entering the diagnostic mode. Then you will get the trouble codes. The light will blink a number of times rapidly, this is the first number of the code. then it will blink again either once for 1 or several more times for another number. It will repeat each code 3 times then after all the codes are read, it will blink a number 12 3 times again ( exiting diagnostic mode)
example: blink- blink blink ( #12 3 times)
" blink blink blink - blink (trouble code 31 3 times)
if thats all the codes you have, it will blink a #12 3 times
(exit diag. mode) It will give you all codes 3 times. Take a pencil with you to help keep track while your doing it to help keep track. If you don't have a code book, get back to me with the #'s and i"ll give you the code problems.
