I own a snap-on Vantage pro, the German software and plug in devices are an option. Snap-on on is a generic scanners a very well made unite with continuous updates that you must pay for if you work on many different Domestic and foreign automobiles. It is not a Factory tool

If you know the tricks of the trade a good fluke Digital multi meter will get you buy. Unless you plan to see serious and take a good class about scanners and read upon how they work ,spending over $1000,00 will not give you a clue about the problem and may Miss direct you to the wrong part to replace. working with scanners is a way of live know for the new generation of automobiles. It drives the service cost up because the techican has to investigate were the problem originated and what set the mill light on the dash.

I would first invest in a good colledge night course on using scanners to fine problems or read some good books to get an over view of what s involved.
Just having the equipment does not make the problem go away. You have to know were to look and how to read the Factory side of the scanner and the Generic side. invest in learning about mode 06. their are some good sites on the web that can help direct you to places that your money will be better spent.
