ISO 27145-2:2012/Amd 1:2023 is an amendment to the international standard ISO 27145-2:2012, which focuses on the communication requirements for World-Wide Harmonized On-Board Diagnostics (WWH-OBD) in road vehicles. The amendment, issued in 2023, provides updates and revisions to the original standard. Specifically, it addresses the common data dictionary used in WWH-OBD, including elements like diagnostic trouble codes (DTCs) and data identifiers (DIDs). The standard aims to ensure consistent and reliable communication between vehicles and diagnostic tools, facilitating better vehicle maintenance and repair.
