The Informal Working Group on Cyber Security and Software Updates will continue to consider how cyber security and software updates have a bearing on automotive safety and security, and whether any changes are necessary to the Regulations and guidance it has produced under WP.29. In particular, the IWG shall maintain official documents regarding UN R155, UN R156, and Recommendations on uniform provisions concerning cyber security and software updates; develop amendments to relevant documents; develop a proposal to amend UN Regulations under the responsibility of GRVA to record details of an RXSWIN where applicable which have been mandated by the 01 series of UN Regulation No. 156; develop proposals to amend UN Regulation No. 155 and its interpretation document to support application in national/regional frameworks for aspects such as multi-stage manufacturing; consider and develop deliverables regarding software updates after registration potentially creating a proposal for modification to the type approval numbering or a classification of update categories; support and review the application of cyber security and software update provisions across GRs notably for the Global Technical Regulation on Automated Driving Systems; and provide opportunities to participants to share knowledge, experience and ideas from implementation of national regulation/standards regarding CS/OTA as well as UN R155 and R156. The IWG will continue its activities until November 2029.
The agenda and minutes from the 51st session were adopted without comment. The group discussed a status report on Supplement 3 to UN R10.07, updated Terms of Reference, and proposals for the 08 series of amendments, with decision to move submission to 2027/2028 to integrate test modes for automated driving systems. The group reviewed proposals on steer-by-wire systems, CISPR average detector clarification, flicker requirements, and AC/DC charger specifications, concluding that most require further elaboration or revision. The 53rd meeting is scheduled for 1–2 July 2026 in Paris.
The EMC informal group proposes to hold a meeting in Tokyo during the 2nd or 4th week of November 2027, with demonstration venue also in Tokyo. Proposed demonstration content is to be determined for automated driving systems. The meeting contents are subject to change.
Proposal to clarify ADS Active Mode, clarify methods to activate ADS using test equipment or by modifying in-vehicle ADS-related ECU software, clarify test objects for ESA at component-level or system-level, and clarify test methods when ADS cannot be activated in an anechoic chamber, when testing in a non-active state, or when errors occur upon ADS activation. This preliminary proposal is intended for presentation at IWG EMC meetings in autumn 2026.
Agenda includes status of work on GTR and UNR proposals and the Guidance and Interpretation Document (GID), and proposals to resolve open items concerning:
