The UN IWG on Cyber Security and OTA held its 38th session 29 June–1 July 2026 in London with remote participation. The group adopted the provisional agenda and minutes from the 37th session. Three items from the IWG were presented at the May GRVA meeting: multistage vehicle documents to become working documents for September; RXWIN documents with elements in square brackets to be resolved; and SUMs document returned for further discussion. For R155, the group agreed to forward multistage amendment proposals as working documents to September GRVA. The UK proposal on STU and component approval for R155 was discussed extensively; the UK will draft a proposal for components only. The UK proposal on remote operation for ADS requires further development. The group will review ADS GTR cyber and software provisions. RXWIN proposal documents were adapted; R155 was removed and R89 and R156 sections amended; reviewers may address concerns by 31 July 2026. Germany’s proposal requiring the same Type-Approval Authority for CSMS and vehicle type approval was discussed; a dedicated meeting will be scheduled. The UK proposal on approvals for out-of-scope vehicle types was introduced. Draft Terms of Reference were revised and will be forwarded to GRVA for September approval. The next meeting is scheduled for 3 September 2026, 12:00–15:00 CET.

Proposal to insert provisions on software identification and software updates into UN R13, UN R13-H, UN R79, UN R89, UN R130, UN R131, UN R152, UN R155, UN R156, UN R157, UN R171, UN R175, and UN R178 by adding definitions referencing Consolidated Resolution R.E.3 Annex 7, requiring manufacturers to provide Technical Services with information on hardware and software influencing performance, permitting vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles, clarifying that production discontinuation does not apply when manufacturers seek approval extensions for software updates of registered vehicles, and amending communication forms to include software identification numbers and related information.

Results of the review of proposals for UN Regulations R28, R51, R64, R138, R141, R142, and R165 regarding autonomous vehicle readiness. Key findings include: inconsistent Mass in Running Order definitions between R51 and R138 versus RE3; unclear special testing provisions in R64, R138, and R165; need for clarification on ADS optical and logical signal transition in R64; redundant full definitions from RE3 in multiple proposals should reference RE3 via footnote instead; inconsistent ADS activity terminology across R64, R141, and R165 should be standardized; incorrect Category Y references in R51 Table 2; and definition and spelling errors in R51, R138, R141, and R165.

The UN IWG on Cyber Security and OTA will meet April 21-22, 2026 via video conference. The agenda includes adoption of the provisional agenda and minutes from the previous session, proposals for amendments to UN R155 and its interpretation document regarding multistage vehicles and type approval authorities, review of cyber and software requirements in the ADS Regulation, discussion of RXSWIN application, renewal of the IWG mandate expiring November 2026, and confirmation of next steps.

UN R156 requires administrative provisions under the 1958 Agreement to demonstrate that vehicles comply with its requirements at specific points in time, not solely at market placement. The action plan involves developing a numbering system for amending approval extensions to account for software updates, considering how updates impact existing type approvals, and reviewing related 1958 Agreement aspects.
