@peplin, thanks much for the reference! It looks like they are in fact using the OBD interface but are documenting it more fully. I wish I would have had something like this for my Corvette. On that car and on my wife's Chrysler van my scanner only interprets the generic codes. It certainly doesn't provide programming information as does this site for the Mustang.
Hey Larry, the data available is listed here, through a link in the Ford-specific section: http://openxcplatform.com/hardware/vehicles.html and there is lots of information on the supported hardware interfaces (including open source hardware options): http://openxcplatform.com/vehicle-interface/hardware.html
It is a great move but a lot of car lovers are already changing computer data to improve engine power and twist the performance of the car. In addition, if general public can start twisting performance of an engine w/o enough understanding, there might be concern to not only Ford Motor but also to the safety of road users.
Great move from Ford. Only an american company could have been the first to do such a change in the global way of thinking. I hope the other car makers will follow. I also hope it will not be limited to the usual ODB Codes that everybody already know. It could be extended to diagnostic control codes, calibration procedures, options/extensions configuration and these stuff that remain closed today.
@Larry, thank you. It's interesting and 'silly' as you say that they limit the access to code because they want to give an advantage to repair shops. Meanwhile, I thought it was for the sake of 'security' of a car. Have I been misled?
There are a set of generic codes which are published and additional codes that automotive manufacturers have held as proprietary. The proprietary codes are usually available to scanners by or under contract to the manufacturers and very expensive. The scanners that are buyable for reasonable cost at automotive stores have limited or no access to the proprietary codes. In my opinion, this is silly and eliminating that silliness would be a good step towards increased openness. Why is it that way? To give their repair shops an advantage in repair business.
