on the standardised data link connector according to the specifications given in section 6.8.

             6.6. The software calibration identification number as declared in Annexes II and VI to Directive 2005/55/EC shall be made available through the serial port of the standardised diagnostic connector. The software calibration identification number shall be provided in a standardised format.

             6.7. The vehicle identification number (VIN) number shall be made available through the serial port of the standardised diagnostic connector. The VIN number shall be provided in a standardised format.

             6.8. 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).

             6.8.1. The use of either ISO 15765 or SAE J1939 shall be consistent throughout sections 6.8.2 to 6.8.5.

             6.8.2. The on-board to off-board communications link must conform to ISO 15765-4 or to the similar clauses within the SAE J1939 series of standards.

             6.8.3. 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.

             6.8.3.1. The use of an on-board diagnostic facility such as a dashboard mounted video display device for enabling access to OBD information is permitted but this is in addition to enabling access to OBD information by means of the standard diagnostic connector.

             6.8.4. Diagnostic data, (as specified in this section) and bi-directional control information must be provided using the format and units described in ISO 15031-5 or SAE J1939-73 section 5.2.2.1 and must be available using a diagnostic tool meeting the requirements of 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.

             6.8.5. When a fault is registered, the manufacturer must identify the fault using the most appropriate fault code consistent with those given in Sec- tion 6.3 of ISO 15031-6 relating to emission-related system diagnostic trouble codes. If such identification is not possible, the manufacturer may use diagnostic trouble codes according to Sections 5.3 and 5.6 of ISO 15031-6. The fault codes must be fully accessible by standardised diag- nostic equipment complying with the provisions of section 6.8.3 of this Annex.

              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.

              (1) The use of the future ISO single protocol standard developed in
