However, challenges remain. ISO 14229 defines only the application layer; implementers must still handle session timing, transport protocols (ISO 15765 for CAN), and functional addressing. Moreover, non-compliance or custom extensions by manufacturers can reduce interoperability. Nevertheless, the standard's widespread adoption, from engine control modules to battery management systems in electric vehicles, underscores its indispensability.
To understand Part 3, it helps to look at where it sits in the Open Systems Interconnection (OSI) model:
P2 _CAN_Server: * The enhanced response time allowed if an ECU issues a "Response Pending" (NRC 0x78) message while performing long operations like memory erasing. Common UDS Services Mapped via ISO 14229-3 iso 142293 pdf

In modern automotive engineering, electronic control units (ECUs) govern everything from powertrain systems to advanced driver-assistance systems (ADAS). Diagnosing these complex networks requires a standardized, reliable communication protocol.
