If you have the Autoxray 5000 then there should be directions as to how to use it.
On most vehicles there is a place to plug in the scanner under the dash on the driver's side. You then must follow the directions of your scanner on how to get the readings.
Remember, that you must have a "check engine" light on in order to have codes to read.
Also know that replacing the component that comes up bad is not always the answer. Many times there is something else that is making the component read as defective. This is where good diagnostic skills come in.
It's fine to attach the scanner and read the codes, but if you're not sure how to diagnose it, then it's best to take it to a certified shop and let them do the work. Good luck.
