Anything other then a code reader should have that info in your owners manual of your scanner. I guess you get what you pay for ?? I know the cost of the scanners I use every day cost at least $6k, but Im betting you can get one from a tool manufactor like Snap On, Matco, Mac tools for a lot less. Im guessing $500.. I saw one thsat would give you live data stream,, was really slow, not real suitable for tricky problems, but at least gave you something??
