OEMs only tell authorized mechanics what the codes mean. Most cars have the basic standardized OBD-II codes, and an additional much-more-useful set of codes/diagnostics that are proprietary.
- bluGill 3y agoThey tell the third party scan tool manufactures as well. (for a "reasonable" price - where reasonable can be 6 figures) I used to work on those scan tools, and so I saw the data (I probably shouldn't talk about it - lets just say were reversed engineered their tools often). Many mechanics will read and tell you the codes for free. Auto part stores will as well.
