What does tsb stand for?
Was reading up on repairing chevy trailblazer. Service 4wd light on. A few people were
asking for tsb codes. What are they talking about? Is it something I can do or get?

RIght, and that isn't a code. So you can scan for the obdii codes to see why the light is on. There might be a TSB that has been written up for your issue.
