Proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78.

Proposal to delete passages under paragraph 3.1.15.2. referring to the “prediction of the vehicle deceleration” since no method for doing so is described in the regulation. Moreover, in a self-certification system, the requirement would have to be met for the actual vehicle deceleration. The proposal also substitutes switching between ABS modes for the terms “disable” and “deactivate” for greater clarity. Lastly, the proposal recommends the use of a clearly specified telltale design to signal the ABS operating status rather than to leave this function open to “…any other equivalent unequivocal indication of the disabled antilock brake system state.”
