Additionally, interventions by systems related to the vehicle stability function
(including traction control, trailer stability assist, corner brake control, and
other similar functions that use throttle individual torque control to operate and
share common components with vehicle stability function, and ESC or VSF
intervention on the steering angle of one or more wheels for the purpose of
vehicle stability) may also be indicated to the driver by this flashing optical

…
3.4.1.5. May also be used to indicate the malfunction of related systems/functions,
including traction control, trailer stability assist, corner brake control, and
other similar functions that use throttle and/or individual torque control to
operate and share common components with ESC.

In the case of a CSF intervention which is controlled by an Electronic
Stability Control (ESC) or a Vehicle Stability Function as specified in the
relevant UN regulation (i.e. UN Regulations Nos.13, 13-H or 140), the ESC
flashing tell-tale indicating the interventions of ESC may be used, as long as
the intervention exists, as an alternative to the optical warning signal
specified above.

Paragraph 7.4., amend to read:
"7.4. ESC malfunction detection
The vehicle shall be equipped with a tell-tale that provides a warning to the
driver of the occurrence of any malfunction that affects the generation or

Annex VI
Revised Terms of Reference and Rules of Procedures of the Informal Working Group on Automatically Commanded Steering Functions
I. Terms of Reference
1. The Informal Working Group (IWG) on Automatically Commanded Steering
Function technology (ACSF) shall review the requirements and limitations associated with
ACSF as defined in UN Regulation No. 79. It shall prepare a draft regulatory proposal
regarding advances in control system technology and the transport opportunities provided
by the Vienna and Geneva Conventions.
2. The IWG shall address the following issues:
(a) Review the current speed limitation (10 km/h) with the purpose of permitting ACSF
functionality during interurban journeys.
(b) Define Human Machine Interface (HMI) requirements for communicating between
ACSF-system and the driver (e.g. system status, malfunction, transition).
(c) Define requirements to enable the evaluation of ACSF during periodic technical
inspection.
(d) Outstanding issues identified during the eighty-second session of GRRF shall be
addressed (e.g. ESF).
Constraints:
(a) The driver shall be able to activate and deactivate the system.
(b) The driver shall, at all times, be able to override the system.
3. The group will focus on systems for vehicles of categories N and M.

regulatory proposals. It should consider pre-existing standards (e.g. ISO, SAE and JSAE)
and Regulations from other territories for ACSF developing its proposals.
5. As a first step, the target completion date for the informal group’s work for less
complex ACSF categories shall be the eighty-second session of GRRF in September 2016
(See ECE/TRANS/WP.29/GRRF/2016/45 as amended). Note: Corrective Steering Function
(CSF), ACSF of Categories A and B1 were adopted by WP.29 in March 2017.
6. As second step the target completion date for the IWG work on the ACSF category
which includes a function of a single manoeuver (C1 and ESF) when commanded by the
driver shall be the eighty-fifth GRRF (special session) in December 2017.
7. And then the target completion date for the IWG work [on ACSF Category B2 and
on further consideration whether ACSF Category C2 is necessary] shall be the eighty-
eighth session of GRRF in February 2019.
8. The final decision on regulatory proposals remains with WP.29 and the Contracting
