I am always wondering. Never read anything about it. How should this be used? Thanks.

This port is very useful for DIY. I've gotten codes for engine, airbag system, cruise control, and transmission. In addition you can jump terminals to turn on the Fuel Pump.

Do a search for a list of all the codes (print it out to keep with you) in order to interpret what direction the code is pointing you.
