This app is the most complete OBD II (EOBD) diagnostic trouble code definitions database. This is an ad-supported Lite version, which contains only 1853 description of generic codes from P0001 to P099F. If extended code is accessible in full version, you will get message "This description is available in FULL version"

If you want to get all descriptions you can buy FULL version ( http://goo.gl/hk0ym ) which contains more than 18500 error descriptions for almost 50 car manufacturers.
