Revised proposal pursuant to GRRF discussions 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.

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.

Proposal to allow the use of the flashing electronic stability control (ESC) tell-tale to indicate the intervention of a corrective steering function (CSF) in cases where the CSF is controlled by the ESC (or other vehicle stability function) system. Outside such cases, CSF interventions are indicated by a continuous optical signal displayed for the duration of the intervention.
