This proposal relates to the proposal in document GRSG-116-15. This proposal would:

1. clarify that the application of an AECD approval to other vehicle categories than M₁ and N₁ is not mandatory,
2. align the power supply requirement of Part III, para. 34.1 with the corresponding requirement in Part II, para. 25.1.
3. clarify with regard to para. 34.1 that if the vehicle is equipped with both
   • -a “back-power supply” as listed in para. 35.10.1 and
   • -a “Power supply other than back-up power supply mentioned in paragraph 35.10.1” as listed in para. 35.10.2
   both should be tested according to Annex 9. The “Power supply other than back-up power supply mentioned in paragraph 35.10.1” should indeed only be tested if it is the only power supply for the AECS.
4. Since informal document GRSG-116-15 deletes the existing exemptions in para. 1.3, and hence introduces more severe requirements, the changes should be introduced via a new series of amendments with appropriate Transitional Provisions of 2 years. (In effect, the application of AECS requirements would be based solely on the scope of UN R94 and R95 and no longer takes into account the presence of an airbag and its triggering system. The manufacturers need sufficient time to ensure AECS compliance for new vehicle types and in the same time, the changes should not affect existing vehicle types that were given an AECS type approval already.)
