What is ISO 17840-2:2019?

ISO 17840-2:2019, also known as "Road vehicles - Diagnostic communication over Internet Protocol (DoIP) - Part 2: Transport protocol and network layer services," is an international standard developed by the International Organization for Standardization (ISO). It provides guidelines and protocols for diagnostic communication between road vehicles and external devices or systems using the Internet Protocol (IP).

Transport Protocol and Network Layer Services

The second part of ISO 17840-2 focuses on the transport protocol and network layer services for diagnostic communication over IP. It specifies how data should be transported, organized, and exchanged between a vehicle's onboard diagnostics system and external devices or systems. This includes the transmission of diagnostic messages, handling of diagnostic sessions, and network management.

Benefits and Applications

The implementation of ISO 17840-2:2019 brings several benefits to the automotive industry. First, it enables standardized and reliable communication between vehicles and diagnostic equipment, which facilitates efficient vehicle diagnostics and maintenance. Second, it ensures compatibility and interoperability among different vehicle models and diagnostic systems, allowing for easier integration and exchange of information. Finally, it enhances cybersecurity measures with secure communication protocols, protecting sensitive data and preventing unauthorized access.

Conclusion

ISO 17840-2:2019 plays a critical role in promoting efficient and effective diagnostic communication in the automotive industry. By setting standards for transport protocol and network layer services, it enables smooth and secure interaction between vehicles and external devices or systems. With its widespread adoption, it brings numerous benefits such as improved diagnostic processes, enhanced interoperability, and heightened cybersecurity. As technology continues to evolve, ISO 17840-2 will continue to be updated to meet the changing needs and advancements in the automotive sector.
