The IWG RD-ASEP informal group is developing a mandatory procedure for UN R51 after the monitoring phase. The Analysis Task Force determined vehicle databases and expectation models are suitable for RD-ASEP development. The Editing Task Force created a consolidated R51.04 draft submitted to GRBP-84. The revised R51.04 RD-ASEP includes manipulation and defeat device provisions, mandatory random testing for approval, revised control range, any acceleration position testing, vehicle speed range 0-100 km/hr, and vehicle performance criteria. A revised companion document GRB-68-03 is necessary.
