Proposal to amend Annex 8, para. 3.4.1. to require that the strategy chosen shall not prejudice safe operation of the system due to failures with other systems involved in achieving the function of the system, and amend Annex 8, para. 3.4.4. to require that analysis of system behaviour on fault occurrence includes faults with other systems involved in achieving the function of the system, and to correct ‘safetys’ to ‘safety’. The proposal addresses a collision where tyre failure resulted in unsafe ABS activation. Although the 02 series clarified ABS as part of electronic control systems assessment, it does not explicitly state what is covered, potentially missing relevant faults or failures influencing system function. The additions ensure all relevant faults or failures are accounted for in manufacturers’ safety concept and analysis.

Proposal to insert provisions on Software Identification Numbers and software updates across UN R13, R13-H, R79, R89, R130, R131, R152, R155, R156, R157, R171, R175, and R178 by adding definitions referencing Consolidated Resolution R.E.3 Annex 7 paragraph 2, requiring manufacturers to provide Technical Services with information on hardware and software influencing performance with test reports, permitting vehicle manufacturers to apply for new approvals differentiating software versions for registered vehicles from new vehicles where type approval regulations are updated or hardware changes occur in series production with test duplication avoided where possible, clarifying that production is not considered definitively discontinued if manufacturers obtain subsequent extensions for software updates of registered vehicles, renumbering and inserting new items in approval communication annexes for R13SWIN, R13-HSWIN, R79SWIN, R89SWIN, R130SWIN, R131SWIN, R152SWIN, R155SWIN, R157SWIN, R171SWIN, R175SWIN, and R178SWIN information including whether held on vehicle and relevant parameter identification lists, and amending R157 and R171 to align software update requirements with R156 technical specifications and transitional provisions.
