UN R39 allows for odometer units in miles. This proposal would clarify requirements for systems that can switch the odometer units between kilometers and miles to ensure that only one unit of measurement for total distance is used at a time.

Amendment to include the unit of odometer measurement in the display to resolve concerns over dual-mode systems.

Proposal to amend UN Regulation No. 39 (Speedometer and odometer) to introduce software update references and identification. New provisions add definitions regarding Software Identification Number, refer to Consolidated Resolution on the Construction of Vehicles (R.E.3), Annex 7, paragraph 2. Modifications address production definitively discontinued, software updates for registered vehicles, hardware and software information provision, vehicle approval for differentiating software versions, and additional information regarding software identification. The proposal references ECE/TRANS/WP.29/1175, paragraph 37, and incorporates provisions from R.E.3 Annex 7 to define R39SWIN as dedicated identifier representing type-approval relevant software information.
