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.

Proposal to amend GRVA/2026/27, which proposes amendments to UN R13, UN R13-H, UN R79, UN R89, UN R130, UN R131, UN R139, UN R140, UN R152, UN R156, UN R157, UN R171, UN R175, and UN R178:

• Throughout these regulations, amend references to the Consolidated Resolution on the Construction of Vehicles (R.E.3) as document ECE/TRANS/WP.29/78/Rev.8,
• insert new definitions for Software Identification Numbers referring to R.E.3 Annex 7 para. 2,
• amend requirements for software identification to require manufacturers provide necessary information allowing Technical Services to uniquely identify hardware and software configurations,
• insert new provisions allowing vehicle manufacturers to apply for new approvals differentiating software versions for vehicles already registered in the market from new vehicles,
• amend production discontinuation provisions to clarify production is not considered definitively discontinued if manufacturer intends to obtain subsequent extensions of approval for software updates of registered vehicles,
• insert new items in annexes regarding additional information on software identification and software updates including R_xSWIN identification, whether held on vehicle, how to read if not held on vehicle, and relevant parameters for vehicle identification.

Japan submitted comments on RXSWIN assignment at the 38th CS/OTA IWG. Q.1 asks whether, when a type approval is extended from UN R156-00 to UN R156-01, RXSWIN may be assigned at extension time, and if a UN Regulation refers to RE.3 Annex 7 through a supplementary amendment after UN R156-01 transitional provisions become applicable, whether RXSWIN is assigned at that time. Q.2 asks whether Approval Authorities other than the Authority granting approval are expected to have access to the OEM’s Auditable Register, as access information appears provided only to the Approval Authority concerned through paragraph 9.5.2. Q.3 asks whether software updates affecting type approval can be performed under Regulations that do not reference RE.3 Annex 7.

The UN IWG on Cyber Security and OTA issues held its 39th session on 3 September 2026. The provisional agenda (TFCS-38-01/Rev.3) and minutes from the 38th session (TFCS-38-13) were adopted. Regarding R155 amendments: multistage vehicle proposals (GRVA/2026/28, GRVA/2026/29, TFCS-39-08) will be submitted as informal documents with a merged paragraph; component approval proposals (TFCS-39-04) had STU references removed and discussion continues; remote operation for ADS proposals were not discussed but participants are invited to consider a general refresh of Annex 5. RXWIN application proposals (TFCS-39-05, TFCS-39-06, TFCS-39-07, TFCS-39-08, TFCS-39-09, TFCS-39-10, TFCS-39-11, TFCS-39-12) were presented; items 1, 4, and 6 were agreed, item 5 was agreed in principle, and items 2 and 3 regarding R155 and R157 applicability require revised wording. Netherlands expressed concerns about vehicle discontinuation and multiple type approvals. Administrative provisions regarding Type Approval Authority for CSMS/SUMS (GRVA/2026/30, TFCS-39-02, TFCS-39-07) were discussed without consensus. Out-of-scope vehicle approvals (TFCS-38-03) discussion was deferred to a separate workshop. Two informal documents will be provided to GRVA.
