OBD-II Diagnostic Tools
OBD-II Diagnostic Tools Page
In my search for OBD-II Diagnostic tools I have found the following links.
http://www.scantool.net - This particular site has low cost OBD-II module and an open-source software. The free software has enough functionality to save you big bucks on it's own, but if you feel like tinkering with the software, then you could probably significantly expand the capability. I find the open-software a very interesting feature for this tool.
http://www.thinkythings.org/obdii/ - Check out this quick little How-To to see how easy it really is to get data from your car.
http://www.obddiagnostics.com/ - Here is another site that I find useful. It has the right combination of easy use for the person looking for diagnostics, and it has sample programming code and electrical schematics for the DiY guy (ok! ok! and gals).
http://www.obdscan.net/ - This is the site where I bought my OBD-II scan module. About 5 years ago there were not too many choices and this was one of the cheapest I found. The software has improved greatly over the years and I have saved hundreds of dollars diagnosing my cars and probably thousands of dollars helping friends and family. This is a well developed and mature product line. I have used this product on an old laptop running Win98, which has kept me from some of the newer software, but I am testing the newer software now.
http://freediag.sourceforge.net/ - Here is a open-source program to interface with OBD-II hardware. Typical of open-source projects, they start with a good idea, they get it to work, and then little to nothing happens after that. However, the kool factor is definitely present. A great place to learn code for communication with OBD-II hardware, but I doubt many will find this a useful tool compared with what is available today.
