ISO 14229-1 is the primary international standard for . It defines the application layer requirements for automotive diagnostics, allowing a diagnostic tester (client) to communicate with an on-vehicle Electronic Control Unit (ECU, server). Because it is data-link independent, UDS can operate across various networks including CAN, Ethernet (DoIP), LIN, and FlexRay. Core Concepts of ISO 14229-1

UDS operates on a principle. A tester tool sends a request containing a Service Identifier (SID), and the ECU responds either positively or negatively.
Uses a seed-and-key exchange to unlock restricted diagnostic functions.
Retrieves real-time values from the ECU.
