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.

The CS/OTA Task Force held its thirty-seventh session on 21-22 April 2026 by video conference. The group adopted the provisional agenda and minutes from the thirty-sixth session. Discussions addressed proposals for amendments to UN R155 concerning multi-stage vehicle approvals and separate technical units, for which a subworking group was established. Proposals were also considered on type approval authority responsibility for cyber security management systems and remote operation of automated driving systems. The group reviewed cyber and software requirements in the ADS GTR and WP.29/2022/60 as amended by WP.29/2023/87, and discussed application of RXSWIN to UN Regulations, selecting option 2 for presentation to GRVA with R155, R156, and R89 square bracketed. The IWG mandate renewal was discussed, with potential new items including component and STU approval and software numbering proposals.
