What UN ECE Regulation 156 - Software Update Management System (SUMS) for Connected Vehicles requires
UN ECE Regulation No. 156 on Software Update Management Systems (SUMS) for Vehicles (adopted by UNECE WP.29, entry into force January 2021, mandatory for EU type approval since July 2022) requires vehicle manufacturers to establish and maintain a certified Software Update Management System governing all OTA (Over-The-Air) and physical software updates to type-approved vehicle systems. SUMS ensures that software updates do not compromise safety, cybersecurity, or type approval compliance. The regulation is sister to UN R155 (CSMS) and both are mandatory conditions for EU type approval under the UNECE 1958 Agreement. SUMS certificates are issued by national type approval authorities after audit of manufacturer's SUMS processes.
