The ISO 14229 series establishes a client-server architecture where an external diagnostic tester (client) controls diagnostic functions in an on-vehicle Electronic Control Unit (server/ECU). Part 1 focuses entirely on the , making it data-link independent. It functions identically whether layered over CAN (ISO 15765), Ethernet (DoIP / ISO 13400), or LIN buses.
Modern vehicles are defined as much by their software as by their hardware, making a unified and powerful diagnostic standard like UDS more critical than ever.
