UN R83: Proposal for Supplement 17 to the 05 series of amendments
|
|
Reference Number: WP.29/2023/61
|
|
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.
