The ISO 14229-1 standard specifies the application layer protocols for diagnostic communication in road vehicles. It operates independently of the underlying physical and data link layers, meaning it can be implemented over Controller Area Network (CAN), Automotive Ethernet (DoIP), Local Interconnect Network (LIN), or FlexRay.

Finding a PDF that incorporates the amendment is currently rare. Most official PDFs are for the base 2020 version. Therefore, when searching for the "new" standard, you need to be aware of both the 2020 revision and its 2022 amendment. A truly "new" PDF would be a consolidated version that includes the amendment's changes. Engineers working on cutting-edge systems must be aware of these updates to ensure their software adheres to the latest specifications, which may include updates to service identifiers or security mechanisms.
The 2020 edition and 2022 amendment introduced critical updates to handle modern vehicle complexities, particularly regarding cybersecurity and data handling: It operates independently of the underlying physical and
