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.

Proposal to amend para. 3.1.2., 12.2.1., 12.2.3., and 12.2.6. to introduce Level 1A, Level 1C, or Level 2 requirements of UN Regulation No. 154 and the 01 series of amendments to UN Regulation No. 168 on real driving emissions. The proposal recognises a new Level for voluntary acceptance by Contracting Parties proposed to be included in UN Regulations Nos. 154 and 168, complementary to proposals to introduce Level 1C in those Regulations.

Proposal to introduce modifications with regard to the
usage of OBM generated data for the part B In-Service Conformity compliance of the light-duty vehicles’ battery durability, including to amend para. 4. to distinguish verification procedures for vehicles with Over-the-Air data transmission versus other vehicles, amend para. 4.3. to clarify pass/fail criteria and vehicle age counting for battery durability families, and insert new paras. 4.4. to 4.6. to establish manufacturer obligations for On-Board Monitoring systems with Over-the-Air functionality, exemptions from certificate provision and additional dataset requirements, and corrective measures for non-compliant battery durability families.

Proposal to:

• Amend Annex 5, para. 5. and 5.1. to introduce verification of reported assessment of virtual distance,
• Insert new sub-paras. 5.1.1., 5.1.2., 5.1.3., 5.1.4. and 5.1.5. establishing environment temperature requirements, initial State of Charge settings, discharging test procedures, test termination conditions, and verification test methods,
• Amend para. 5.2. to establish pass/fail criteria based on statistical evaluation where verification fails if reported delta virtual distance exceeds measured virtual distance by more than 5 per cent, using a decision chart to determine sample pass or fail outcomes.
