In order to facilitate the provision of generic diagnostic tools for multi-make repairers, vehicle manufacturers shall make available the information referred to in points 3.1, 3.2 and 3.3 through their repair information websites. That information shall include all diagnostic tool functions and all the links to repair information and troubleshooting instructions. The access to the information may be subject to the payment of a reasonable fee.

The following information shall be required indexed against vehicle make, model and variant, or other workable definition such as VIN or vehicle and systems identification:

1. (a)

   Any additional protocol information system necessary to enable complete diagnostics in addition to the standards prescribed in Point 4.7.3 of Annex 9B to UN/ECE Regulation No 49, including any additional hardware or software protocol information, parameter identification, transfer functions, ‘keep alive’ requirements, or error conditions.

2. (b)

   Details of how to obtain and interpret all fault codes which are not in accordance with the standards prescribed in Point 4.7.3 of Annex 9B to UN/ECE Regulation No 49.

3. (c)

   A list of all available live data parameters, including scaling and access information.

4. (d)

   A list of all available functional tests, including device activation or control and the means to implement them.

5. (e)

   Details of how to obtain all component and status information, time stamps, pending DTC and freeze frames.

6. (f)

   Resetting adaptive learning parameters, variant coding and replacement component setup, and customer preferences.

7. (g)

   ECU identification and variant coding.

8. (h)

   Details of how to reset service lights.

9. (i)

   Location of diagnostic connector and connector details.

10. (j)

    Engine code identification.

The following information shall be required:

1. (a)

   A description of tests to confirm its functionality, at the component or in the harness.

2. (b)

   Test procedure including test parameters and component information.

3. (c)

   Connection details including minimum and maximum input and output and driving and loading values.

4. (d)

   Values expected under certain driving conditions including idling.

5. (e)

   Electrical values for the component in its static and dynamic states.

6. (f)

   Failure mode values for each of the above scenarios.

7. (g)

   Failure mode diagnostic sequences including fault trees and guided diagnostics elimination.

The following information shall be required:

1. (a)

   ECU and component initialisation (in the event of replacements being fitted).

2. (b)

   Initialisation of new or replacement ECU’s where relevant using pass-through (re-) programming techniques.
