Proposal to insert definitions for Software Identification Number, insert requirements for manufacturers to provide necessary information allowing the Technical Service to uniquely identify hardware and software configurations, insert provisions allowing vehicle manufacturers to apply for new approvals to differentiate software versions for registered versus new vehicles, amend production discontinuation provisions to clarify that cessation is not deemed definitive if the manufacturer intends to obtain subsequent extensions for software updates of vehicles already registered in the market, renumber and insert new items in approval communication annexes regarding software identification and software updates including RxSWIN, and insert provisions allowing vehicle manufacturers to obtain new approvals for software version differentiation across multiple UN Regulations (13, 13-H, 79, 89, 130, 131, 139, 140, 152, 155, 156, 157, 171, 175, and 178).

Proposed changes to align RxSWIN provisions with the RxSWIN template adopted through WP.29-197-06, remove the proposed requirement to comply with UN R156/01 or later from R157 and R171, remove amendments to UN R155 as decided by the IWG CS/OTA, apply the RxSWIN amendments also to earlier series of amendments in R13, R13-H, R79, R131, R152, R157, and R171, update references to the latest version of R.E.3, ECE/TRANS/WP.29/78/Rev.8, in earlier series, and correct paragraph references and improve structure in R89, R139, R140, R155, R156, and R171.

GRVA held its twenty-fifth session on 23 June 2026 in Geneva, following consultations in Montreal from 18-22 June 2026. The working party endorsed status reports from informal working groups on Automated Driving Systems, cyber security and over-the-air updates, acceleration control for pedal error, advanced emergency braking systems, and event data recorder/data storage systems. GRVA adopted amendments to UN Regulations 79, 90, 152, 157, and 178, and amendments to documents on automated driving systems for submission to WP.29 and its administrative committees. GRVA established a task force on Exchange of Scenario-Relevant Information, extended the mandate of the Informal Working Group on Automated Driving Systems for three years, and agreed to pause activities of the Task Force on Advanced Driver Assistance Systems and install a task force for exchange on Automated Driving Systems implementation. GRVA noted various proposals on cyber security, data protection, connected vehicles, and advanced driver assistance systems for further consideration.

Session report of WP.29 (World Forum for Harmonization of Vehicle Regulations), its Administrative Committee of the 1958 Agreement (AC.1), Executive Committee of the 1998 Agreement (AC.3), and Administrative Committee of the 1997 Agreement (AC.4) held 23-26 June 2026 in Geneva. AC.1 voted on 92 amendments to existing UN Regulations, one corrigendum to UN Regulation No. 79, and three new UN Regulations (Nos. 184-186) on liquid hydrogen vehicle safety, automated driving systems, and tyre abrasion performance. AC.3 established UN GTR on automated driving systems and adopted corrigendum to UN GTR No. 9 and Amendment 2 to UN GTR No. 13. WP.29 extended mandates of several informal working groups and noted accession of Mongolia and Armenia to the 1958 and 1997 Agreements respectively.

Proposal to amend UN R13, 13-H, 79, 89, 130, 131, 139, 140, 152, 155, 156, 157, 171, 175, and 178 by introducing provisions on software identification and software updates. Amendments add new paragraphs referring to Software Identification Number definitions in Consolidated Resolution R.E.3, require manufacturers to provide Technical Services with information on hardware and software influencing performance, permit vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles while avoiding test duplication, and modify production discontinuation provisions to exclude cases where manufacturers seek approval extensions for software updates of registered vehicles.

Proposal to insert new paragraph 1.2.3 relating to vehicles of categories X and Y, amend footnotes 1 and 3 to reference the Consolidated Resolution on the Construction of Vehicles (R.E.3.), document ECE/TRANS/WP.29/78/Rev.8, and insert new paragraph 5.7 stating that while an ADS feature is active, the BAS shall not influence the performance of the braking system.
