Howdy Folks,

First time poster here

I am reading my check-engine codes and I am getting (1) flash of code 12 then we get 5 consistent flashes - pause - then 3 flashes (the pause is pretty significant) and it does this (3) times. Then we get 6 consistent flashes - pause - 3 flashes and cycles (3) times.

These (2) codes seem to be 53 and 63 right..? Well everywhere I have read says code 12 will flash (3) times, not in my case.. Also everyone has said it will revert back to code 12 when completing the code reading cycles, not in my case -- the 53 and 63 codes keep repeating and repeating and repeating...

Any input would be awesome!

 

I do not get code 12 on my 1995, only when no other codes are present, to clear codes I believe you need to press on both brake and gas pedal while reading codes, hold down on both until they clear and then code 12 should flash. I believe that is the way I used to do it, I have GMTD Scanner now and have not done it that way for a while. Hope that helps.
