I know the first line was the errror code, the rest of the stuff is gibberish to me.

You should read your manual that came with the reader, but if I'm reading this right, the first line shows the error code. The next line is saying your CEL light is on. The line after that is saying there are 4 incomplete monitors that are not ready to be read, and then lists them. Then, it shows the other 4 that are complete and ready to monitor. This info is useful if you are planning to get your state inspection, recently cleared any codes and want to know if you've driven enough to reset all the monitors.
