The proposed language aims to harmonize and improve the requirements to indicate the intervention of ESC-related systems across the main braking regulations, i.e. FMVSS 126, GTR 8, UNECE R13H and R13.

OICA has proposed following the essence of FMVSS 126 as the clearest regulation in this respect because it indicates in that manufacturers “…may use the ESC malfunction telltale in a flashing mode to indicate operation of these ESC-related systems”.
