Proposal to amend UN R180 to incorporate vehicles with Automated Driving Systems. Changes include adding ADS abbreviation and definitions for “ADS user” and “Vehicle user”; amending terminology throughout from “driver” to “vehicle user” or “driver and/or ADS”; introducing the Excess Exhaust Emissions Driver/user Warning System definition; modifying accelerator pedal references to include torque demand from ADS; and clarifying that warnings shall be sent to the ADS, which will then inform the relevant ADS user.

GRPE held its ninety-fourth session from 17 to 19 March 2026 in Geneva. GRPE adopted proposals for draft supplements and amendments to UN Regulations Nos. 68, 83, 154, 49, 24, 85, 115, 133, 143, 177, 96, and ¹⁷⁹, and to UN GTRs Nos. 21, 22, and 25, requesting secretariat submission to WP.29 and AC.1 or AC.3 for consideration and vote at their June or November 2026 sessions. GRPE adopted ECE/TRANS/WP.29/GRPE/2026/27 and requested secretariat submission to WP.29 for consideration at its November 2026 session as draft new Revision 2 to M.R.3. GRPE agreed to postpone consideration of certain proposals to forthcoming sessions. The next GRPE session is scheduled for 14–16 October 2026.

Proposal to amend the scope to allow type approval of vehicles of categories M₁, M₂, N₁ and N₂ with a reference mass not exceeding 2,840 kg at the manufacturer’s request as an extension from vehicles with reference mass not exceeding 2,610 kg, and to allow type approval of special purpose vehicles of categories M₁, M₂, N₁ and N₂ regardless of their reference mass at the manufacturer’s request, with the manufacturer demonstrating to the Type Approval Authority that the vehicle in question is a special purpose vehicle.

Proposal to amend the scope to allow type approval of vehicles of categories M₁, M₂, N₁ and N₂ with a reference mass not exceeding 2,840 kg as direct approvals rather than only as extensions based on approved configurations below 2,610 kg. The modification permits manufacturers to obtain type approval for vehicles within the 2,610 kg to 2,840 kg reference mass range regardless of whether lower-mass configurations of the same vehicle type are approved, addressing concerns that the previous restriction created market distortions affecting different manufacturers differently, a concern heightened by fleet electrification.

Proposal to amend para. 1 to clarify that type approval may be granted to vehicles of categories M₁, M₂, and N₁ with a reference mass not exceeding 2,840 kg at the manufacturer’s request, without requiring an existing approval of a configuration below 2,610 kg. The current wording restricts approval between 2,610 kg and 2,840 kg to extensions of existing approvals, creating market distortion. The concern is becoming more relevant with fleet electrification, as electrified vehicles are heavier and require different type designations in emissions-based regulations.

Proposal to amend para. 3.2.12.2.7.6.3. of Annex 1 to clarify documentation requirements for OBD output codes and data, insert new definitions in Annex 11 for limp-home routines, pending fault code, readiness, confirmed fault code, cold start, and emission control components, amend paras. 3.3.3.5. and 3.3.4.5. to clarify monitoring requirements for emission-related powertrain components, amend para. 3.8.1. to modify fault code erasure criteria, insert new para. 3.8.2. for pending fault code erasure, amend para. 6.5.1. of Appendix I to clarify the meaning of “if available”, amend para. 6.5.3.1. to allow DoIP standards for Pure Electric vehicles from 1 January 2029, amend para. 6.5.3.3.1. to permit SAE J1979-2 and J1979-3 standards, insert new para. 6.5.3.3.2. for DoIP standards, amend para. 7.3.2. to specify when monitor denominators shall be incremented for temperature sensors and boost pressure control systems, and amend para. 1.(e) of Annex 12 to clarify requirements for user-visible active error entries.
