Dyma’r fersiwn wreiddiol (fel y’i gwnaed yn wreiddiol).
The signals must be provided in standard units based on the specifications given in section 6.8. Actual signals must be clearly identified separately from default value or limp-home signals.
The emission control diagnostic system must provide for standardised or unrestricted access and conform to either ISO 15765 or SAE J1939, as specified in the following sections(1).
Test equipment and diagnostic tools needed to communicate with OBD systems must meet or exceed the functional specification given in ISO 15031-4 or SAE J1939-73 section 5.2.2.1.
The manufacturer shall provide a national standardisation body with emission-related diagnostic data, e.g. PID’s, OBD monitor Id’s, Test Id’s not specified in ISO 15031-5 but related to this Directive.
The manufacturer shall provide a national standardisation body with emission-related diagnostic data, e.g. PID’s, OBD monitor Id’s, Test Id’s not specified in ISO 15031-5 but related to this Directive.
As an alternative, the manufacturer may identify the fault using the most appropriate fault code consistent with those given in SAE J2012 or in SAE J1939-73.
In the case of category N2, N3, M2, and M3 vehicles, as an alternative to the connector location described in the above standards and provided all other requirements of ISO 15031-3 are met, the connector may be located in a suitable position by the side of the driver’s seat, including on the floor of the cabin. In this case the connector should be accessible by a person standing outside the vehicle and not restrict access to the driver’s seat.
The installation position must be subject to agreement of the approval authority such that it is readily accessible by service personnel but protected from accidental damage during normal conditions of use.
The use of the future ISO single protocol standard developed in the framework of the UN/ECE for a world-wide global technical regulation on heavy-duty OBD will be considered by the Commission in a proposal to replace the use of the SAE J1939 and ISO 15765 series of standards to satisfy the appropriate requirements of section 6 as soon as the ISO single protocol standard has reached the DIS stage.
