Under the proposed international whole vehicle type approval, Annex 4 to the regulation would provide the list of component regulations. Annex 4 will be updated over time to incorporate new or updated regulations that comprise a whole vehicle approval. These changes in requirements will impact whether a vehicle has a universal or limited approval and will require communication between the holder of the approval and the issuing type approval authority; however, the obligations and procedures for maintaining this coordination are not spelled out in the UN R0 text. Japan proposes a manufacturer obligation to notify of the authority of its intentions when an amendment to Annex 4 would impact an existing approval in its possession.
