I'm not sure how far you've went here. What I mean is, if you know the original 16 flashes is just to tell you that there is a concern. It's not a trouble code in itself.
You have to do the "turn off key, shift to 1, push in the manual button, etc.) routine to get the real trouble code. In my case, do it 3 or 4 times before it works.
Go here:

and click on the "codes" link at the top. At the bottom of the next page is a link to get you what you need. It has both the sequence to get to the real code, and also all the trouble codes.
