Hey all,

Since I am still green at working on the PSD, I see everyone saying run a buzz test and contribution test. What does each test do and how do you do the test. I currently do not have a good scan tool, so I would have no way to pull codes. I just would like to know how to d them just in case, so I am not posting in the 911 area.
Thanks for the info ahead of time.
