93 lumina fault codes has 5 fault codes 15 23 43 53 66?

Answer 1

if i had a manual for the lumina 1993 3.1 v6 i'd look in the index in back of book and look for trouble codes and look up that page and it will show you all the codes starting with code 12 and when you put say a paper clip or a key with 2 prongs on the end (from auto zone-free) and insert it into the top right last two squares (will have metal clips in them) located under bottom of dashboard below steering wheel (bout 2 in. long and maybe 3/8 to 1/2 high). have ignition off PUT in key. make sure your paper clip or key is inserted into those 2 top right sqares so you are making a circut like a U into those 2 sqares like i told you b4. now turn on ignition but NOT starting the engine. wait a few seconds and the service engine light will blink once then twice. it will normally do this 3 times. in other words 1blink pause 2blinks pause 2 more times. that is saying code 12. now if their are other codes after that i.e. 4blinks pause 5blinks pause (3 times) then that's code 45. if more codes it will do the same. if it goes back to code 12 (3 times) then you are finished. i hope this may help a lot of folks out there.
