Error Code 20

[SteelAveo]

Hi folks, hoping you can help me out here. I have a 2012 Chevy Aveo LT and all through today whenever i start the car i get error code 20 showing on the dash. I cant find what this relates to anywhere and wondering if anyone could help me out before I go get charged by a garage for something that could be nothing.
Thanks!

unfortunately that car is a sonic here in the states, and not so much part of this forum.

having said that, it is a head light burned out.

here is a list for you to copy:

Ah I didnt realise there was a different kind of Aveo in different countries (USA and UK at least). What a confusing way to run the business haha. But thanks a lot for the answer and the list which I will defo be keeping a copy of!
