Proposal for changes to the draft amendments to the 05, 06, and 07 series per the following justifications:

1. In GRPE-86-12, the introduction of SAE J 1979-2 was proposed for Series 05, 06 and 07 of Regulation No. 83. Due to the different structure of Series 05 and 06 compared to 07, this proposal was not adopted. This proposal introduces the new standard to Series 05 and 06 and aligns the standards with Series 07.
2. The standards used for transmission of OBD information are maintained by international standardisation bodies (ISO, SAE). These standardisation body have to be informed.
3. Alignment of wording between the first sentence of paragraph 3.2.1.2. (“ambient or engine temperatures”) and the second sentence, where “or engine” was missing to avoid misunderstanding and ambiguity. Engine temperature is sometimes used as a substitute for ambient temperature. In this case, the engine temperature is evaluated once after a longer engine shut off phase. Only in this case an approval is necessary, as this is the only case, where an OBD monitor is disabled for the complete trip.
4. Align Paragraph 6.5.1.3. with GTR No. 15 to avoid ambiguity.

Proposal of amendments to promote harmonization, legal certainty, and environmental protection in the 08 series of amendments.

Additional information concerning the 08 series of amendments pursuant to UN R154 (WLTP) and work on real-driving emissions testing.

Proposal to extend to the 05 series of amendments the option from the 06 and 07 series to use the calculation of road load values determined according to UN GTR 15 (WLTP).

Proposal based on the 07 series of amendments to remove elements covered by UN R154 (WLTP), to include references to the draft UN Regulation on Real Driving Emissions (RDE), and to update In-Service Conformity (ISC) requirements for the purposes of establishing regional type approval equivalence.

Proposal to introduce SAE standard J1979-2 (E/E Diagnostic Test Modes: OBDonUDS) as an option into the Regulation and 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 missing to avoid misunderstanding and ambiguity. Engine temperature is sometimes used as a substitute for ambient temperature. In this case, the engine temperature is evaluated once after a longer engine shut off phase. Only in this case an approval is necessary, as this is the only case, where an OBD monitor is disabled for the complete trip.

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.

Proposal to extend the option from the 06 and 07 to the 05 series of amendments allowing the calculation of road load values from those determined according to UN GTR No.15 (WLTP).

Proposal to introduce corrections and clarifications for the 08 series of amendments.

Proposes some amendments to working document ECE/TRANS/WP.29/GRPE/2024/8 introducing change stop footnotes to Table A3/1 and makes changes to the transition provisions
