Not sure how similar the Colt ECU is to a 1g (I think they are the same no?) But this is on vfaq, and instructions on how to retrieve the code if you don't have a logger.
http://www.vfaq.com/index-main.html
Electrical>Retrieving Diagnostic Error Codes
There should be a list of codes along with instructions in there.
Again, not sure how similar this is to a 1g, but I figure it's worth a shot.
