The increasing complexity of automotive electronics and the need for standardized diagnostic communication protocols have led to the development of ISO 13480. Specifically, Part 4 of this standard, ISO 13480-4, focuses on diagnostic communication over Controller Area Network (CAN) for road vehicles, with an emphasis on requirements for emissions-related systems.

Division 4 was introduced in the edition and refined in the 2023 edition . It addresses a critical gap: the safe design of vessels subject to hydrogen embrittlement and rapid gas cycling (e.g., hydrogen refueling stations, Type I and Type II high-pressure cylinders). The increasing complexity of automotive electronics and the
