18. The expert from OICA introduced GRPE-79-15, GRPE-79-16 and GRPE-79-17 proposing modifications to the 07 series of amendments to UN Regulation No. 83 on On-Board Diagnosis (OBD). The representative from Netherlands, France and EC required more time to analyse the proposals and to consult internally with the appropriate experts on OBD. The representative from EC requested a more thorough assessment and more detailed specifications of the needs and requirements to amend the regulatory text. The Chair acknowledged that the specific expertise on OBD from CPs was in most cases not present in the room and proposed OICA to further develop the proposals and submit as working documents for the next session of GRPE in January 2020.
