Document Title	Adopted amendments to GRRF/2017/23 (UN R13, 13-H, 140)
Reference Number	GRRF-84-39
Date	24 Sep 2017
Summary	Revised proposal, as approved during the 84th GRRF session, to enable activation of the ESC optical symbol in cases of a corrective steering function intervention when the CSF intervention is activated under the control of an ESC system. The aim is to avoid separate requirements for brake-actuated and steering-actuated vehicle stability functions (VSF) that would lead to two optical warnings where only one is necessary. This would enable use of the ESC intervention tell-tale for CSF steering intervention.
Rulemaking Area(s)	UN R13 Heavy-Duty Braking, UN R13-H Light Vehicle Braking, UN R140 ESC Systems, and UN R79 Steering Equipment
Proposal Status	Superseded
