Refinements to the proposal to align the GTR text with updates to UN R78 introduced in response to technological progress in motorcycle braking.

54. The expert from Italy introduced GRVA-02-07 proposing amendments to the original proposal (ECE/TRANS/WP.29/GRVA/2018/9) for amendments to UN GTR No. 3 for harmonization of the GTR and UN Regulation No. 78. The proposal received some comments. The expert from the Netherlands asked why the proposal contained technical requirements that differed from those in UN Regulation No. 78. The expert from Canada highlighted some formulations that could be better defined to facilitate the implementation of the UN GTR into Self Certification regulations.

Proposal to ensure consistency between GTR 3 and UN R78 in light of the proposed amendments to GTR 3 (GRVA/2019/23). Paragraph 5.1.17 aims to clarify with an explicit article that the rider is duly informed when activating a riding mode that disables the ABS on the rear axle.

65. The expert from IMMA introduced GRVA-04-05 and GRVA-04-06, analysing discrepancies between UN GTR No. 3 and UN Regulation No. 78. GRVA invited the expert from IMMA to submit an amendment proposal to UN Regulation No. 78 for review at the next session.

Proposal for editorial corrections and clarifications concerning activation of a riding mode with ABS disabled. The changes are also being concurrently proposed for UN R78.

62. The expert from Italy introduced ECE/TRANS/WP.29/GRVA/2019/23, proposing amendments to UN GTR No. 3 as per the mandate adopted by A.C.3 (ECE/TRANS/WP29/AC.3/47). He also introduced GRVA-04-23 including amendments addressing comments received on the proposal. GRVA adopted the proposal as amended with the below correction and requested the secretariat to submit it to the Executive Committee AC.3 for consideration at vote at its March 2020 session.

In ECE/TRANS/WP.29/GRVA/2019/23, para 10, for 5.1.17, read 3.1.17.

63. The expert from Italy also introduced GRVA-04-24, containing the technical report associated to the proposal. GRVA adopted it and requested the secretariat to submit it to the Executive Committee AC.3 for consideration at vote at its March 2020 session.

64. The expert from IMMA stated his satisfaction concerning the adoption of the amendment proposal to UN GTR No. 3. He mentioned that the outcome of this work was not fully harmonized, especially concerning Electromagnetic Compatibility and defeat device requirements.

Proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78 while addressing its use under self-certification compliance systems.

50. GRVA agreed with the suggestion of expert from Italy to postpone the consideration of this item until the January 2019 session.
