Proposal to harmonize the requirements of the 06 and 07 series of amendments, align with UN R48 wording to ensure consistent type-approval test conditions with the introduction of the 08 series of amendments (to introduce the possibility to switch OFF rear position lamps and other lamps when ambient light conditions outside the vehicle are above 7,000 lux in order to avoid unnecessary fuel consumption), to introduce the option to use of SAE standard J1979-2 (E/E Diagnostic Test Modes: OBDonUDS), to align wording between the first sentence of paragraph 3.2.1.2. (“ambient or engine temperatures”) and the second sentence (where “or engine” was omitted), and to align paragraph 6.5.1.3. with GTR No. 15.
