Application Summary AI generated
This standard specifies the application layer protocol for diagnostic communication over the K-Line in road vehicles, defining message formats, timing, and service procedures for vehicle diagnostics. It is applied in automotive repair and manufacturing contexts, enabling diagnostic tools to communicate with electronic control units (ECUs) in vehicles that use K-Line interfaces, particularly for older or cost-sensitive models. The standard ensures interoperability between test equipment and vehicle systems during fault diagnosis, reprogramming, and routine maintenance.
