A simple OBD II code reader can be a valuable tool for car owners. One such tool, the Innova code reader, works effectively with a 2001 Mercedes SLK, allowing for diagnostics and clearing nuisance codes. This highlights the standardized protocols used by car manufacturers for OBD II systems.
While these tools are helpful, the increasing complexity of post-1996 vehicles, with their extensive emissions systems and mandatory OBD-2 data dumps, can lead to expensive repairs and inspection failures. One minor issue can trigger the OBD-2 system, causing significant problems.
Furthermore, newer vehicles often have hidden data-logging capabilities that record driving information. This data can potentially be used by insurance companies or law enforcement in accident investigations. This raises privacy concerns for some drivers.
