16. The expert from the Kingdom of the Netherlands, introduced the status report (GRSG-128-04) of TF on UN Regulation No. 39 on Mileage Values. He explained that the TF had finalized its work and that a proposal was ready for discussion (ECE/TRANS/WP.29/GRSG/2024/36). He clarified that the proposal introduced requirements on malfunction indication in the case of electrically detectable failure and several (editorial) amendments. He also added that L-category vehicles were exempt from the anti-tampering and malfunction indication requirements. The expert from OICA proposed (GRSG-128-20) to remove the speedometer double indication item and paragraph 5.1. since it had not been discussed during the task-force meetings. The expert from Sweden also supported longer transitional provisions (TPs), since manufacturers are not responsible for tyres (as it had been demonstrated these affect the accuracy). The experts from Japan and Sweden supported request for longer TPs. The expert from United Kingdom supported the full text of paragraph 5.1. (without square brackets) and the accuracy value of 4 per cent. Therefore, GRSG considered GRSG-128-02-Rev.3 to be compromise proposal. Finally GRSG adopted ECE/TRANS/WP.29/GRSG/2024/36, as amended by annex IV to this report. The secretariat was requested to submit ECE/TRANS/WP.29/GRSG/2024/36 as a proposal of the 02 Series of Amendments to UN Regulation No. 39, for consideration and vote at the March 2025 sessions of WP.29 and AC.1.
