The J1699 Project on SourceForge

This project is an Open-Source (GPL) implementation of the SAE J1699 test specification. SAE J1699 is an SAE standard for testing cars for compliance with CARB/EPA OBD II mandates, built upon the J2534 Pass-Thru device API. If you don't know what any of that means, then it's a good bet that this software won't be useful to you.

If you would like the software, go to the J1699 Project Page and click on the big green 'Download' button. Download the latest .zip file and expand with WinZip or the like. We have included a pre-compiled J1699.exe for those without software wizard skills. (Usually in the Release/ directory.) You will need a J2534 Pass-Thru device and an OBD-II vehicle (usually MY1996 or later). Most vehicles will fail some part of the test, don't be alarmed. Some of the tests are not mandated until 2008. After running, there will be a .log file that contains a log of everything that happened. The log file is extremely useful for troubleshooting purposes.
