Proposal for amendments to ECE/TRANS/WP.29/GRRF/2015/41
Document GRRF-81-28/Rev.1
5 February 2016

Revised proposal to align UN R78 with the provisions for anti-lock braking systems used in other regulations, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle. This revised proposal takes into account comments received during the February 2016 GRRF session.

4.13.1. | Proposal for the 04 series of amendments to Regulation No. 78 (Braking (category L vehicles))

82. The World Forum considered the draft proposal for amendments to existing Regulations under agenda item 4.13.1 and recommended its submission to AC.1 for voting subject to the amendments below:

83. Agenda item 4.13.1, in ECE/TRANS/WP.29/2016/114, new paragraph 5.1.16, items (e) and (f), amend to read:
New paragraph 5.1.16, item (e) and (f), amend to read:

“(e) The disablement of the antilock brake system function shall be indicated by the activation of symbol B.18 as specified in ISO 2575:2010 (ISO 7000-2623) or any other equivalent unequivocal indication of the disabled antilock brake system state. Alternatively, the warning lamp referred to in paragraph 5.1.13. shall be continuously activated (i.e. lit or flashing); and

4.9.8. | Proposal for Supplement 3 to the 03 series of amendments to Regulation No. 78

59. Agenda item 4.9.8, Regulation No. 78, ECE/TRANS/WP.29/2016/56, amend to read:
Page 3, the proposed insertion of a new paragraph 5.1.16, shall be deleted.
Page 4, the proposed amendment to paragraph 9, shall be deleted.

5. (a) | Regulation No. 78

21. GRRF agreed with the proposal of the expert from EC to reintroduce ECE/TRANS/WP.29/GRRF/2015/41 under agenda item 5(a) and to reconsider the proposal clarifying the possibility to install means to disable the ABS function in certain conditions for L-category vehicles. The expert recalled that a majority of experts expressed specific concerns related to the condition (f) in the proposal at the previous session and therefore agreed to delete it, as shown in GRRF-81-28. The proposal, received some comments to amend the text in a more stringent manner. The expert from IMMA advocated for transitional provisions aligned with those of Euro 5 in Europe. He added that the newly proposed wording was too restrictive and may exclude some vehicles that were already equipped with the feature. GRRF agreed therefore on longer transitional provisions for existing vehicle types, and also to not excessively restrict the kind of vehicle that could be equipped with the ABS off switch function, by softening the wording of these provisions. The Contracting Parties agreed on the amended proposal GRRF-81-28-Rev.1. The expert from Italy expressed a scrutiny reservation on the provisions related to the off road switch. GRRF adopted the proposal as reproduced in Annex III and requested the Secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as a new 04 series of amendments to Regulation No. 78, subject to final review by GRRF in September 2016.
