85. The secretary of the IWG on Periodic Technical Inspection (PTI), representative from CITA, on behalf of the Co-Chairs of the IWG on PTI (the Netherlands and the Russian Federation), introduced ECE/TRANS/WP.29/GRPE/2023/9 and GRPE-89-24-Rev.2. He reminded the adoption of ECE/TRANS/WP.29/GRPE/2023/9 had been postponed at the January 2023 session of GRPE.

86. The representative of the European Commission asked whether this proposal would be formally adopted by GRPE. The Chair confirmed GRPE can adopt documents pertaining to any of the three agreements, and he encouraged GRPE to adopt this proposal during this session if possible.

87. The representative of the UK asked to elaborate on the square brackets around the emission limit still present in the proposal. The Chair confirmed this has to be agreed by GRPE.

88. The representative of the Netherlands explained the country as adopted a high limit value to avoid false negative and ask about the legal meaning of the sentence about mutual recognition under para. 3.2.2.

89. The representative of Germany informed GRPE that the country was about to start PN measurement at PTI in July 2023 and asked whether there was any discrepancy between the EU recommendation published recently and this proposal. The secretary of the IWG on PTI confirmed both text contained identical provisions.

90. The representative of the European Commission and Germany requested to make sure the PN limit would only be available from Euro 5b onwards for light duty vehicles. The representative of Australia also request to ensure the PN limit would only be available from Euro VI trucks.

91. GRPE adopted ECE/TRANS/WP.29/GRPE/2023/9 as amended by GRPE-89-24-Rev.2 as reflected in Annexes V and VI to the session report and requested the secretariat to submit it to the November 2023 session of WP.29 and AC.4.

92. The secretary of the IWG on PTI introduced GRPE-89-07. The representative of CITA supported the proposal and proposed to go ahead with the adoption of the ToRs providing the IWG on PTI also agreed with this proposal.

93. GRPE agreed with this approach and looked forward to some updates about the activities of the emission anti-tampering task force.

94. The representative of AAPC introduced GRPE-89-21. He requested guidance from GRPE on the best way to proceed to ensure full harmonization for OBD communication protocols in all regulatory tools under GRPE’s purview.

95. The representative of OICA confirmed that for light-duty vehicles, UN Regulations Nos. 83 and 154 were up to date, with a proposal to update UN GTR No. 15 expected for the next session of GRPE. He acknowledged SAE was the leading body on harmonized OBD communication protocols and highlighted the importance to be able to read Data Trouble Codes (DTCs) during periodic technical inspections.

96. The Vice-Chair mentioned OBD were used more widely than for emission related purposes, and that the newly created Vehicular Communication Task Force might be a good place to consider this topic if need be. The representative of OICA invited to reach out to SAE to know more about other OBD applications.
