Document GRRF-84-10

15 September 2017

84th GRRF session (19-22 Sep 2017)

Proposal to

delete paragraph 3.1.15.3 as it is an unnecessary provision under self-certification systems and addresses deceleration measurement criteria referenced elsewhere in the regulation
clarify that the ABS tell-tale must be yellow
delete the prohibition on defeat devices due to the absence of objective and repeatable procedures for assess conformity necessary under self-certification.

Submitted by Canada

Status: Superseded
