In addition to Euro 5 emissions standards, encompassed within this is ISO 19689:2016, which defined the requirements for a standard diagnostic connector as well as carrying on from Euro 4, where OBD2 compliant communication protocols were also to be used.
However, the range of OBD2 data required by this legislation is quite limited and does not extend to manufacturers having to allow access to ALL of their systems and parameters.

While this means that data requirements dictated by OBD2 and Euro 5 can be read more easily, this does not extend to other manufacturer data, manufacturer specific fault codes or indeed service reset functions and component commands, tests, activations or adjustments/calibrations.
So to assume that diagnostics is now a simple system that anyone can access is grossly incorrect.
As you can see above, contact 1 can also be used for any requirement that the motorcycle manufacturer deems suitable. There is no requirement for them to use a standard language or protocol for this pin.
It could be used for programming, commands, or indeed other data not covered under OBD2 requirements.
Also we have not only data avialble via CAN HIGH and CAN LOW, but also K Line data streams.
If a Euro 5 cable is required for your Texa diagnostic system, it will be either AP05 or AP58. Check model coverage and cable selection within your software to confirm which cable is required.

Euro 5 cable selector: start with the model and year
Use 2021 onward as a general Euro 5 screening guide only, not a confirmed manufacturer/model-year compatibility range. A bike's year or Euro 5 status alone does not identify the correct cable. Confirm the exact manufacturer, model, year and cable selection in your TEXA software before ordering.
| Manufacturer / model / year check | Cable option | Connector check | Battery / power requirement |
|---|---|---|---|
| 2021 onward as a general starting point, only where TEXA lists AP58 for the exact manufacturer, model and year. | 3151/AP58 Euro 5 OBD Cable | Match the motorcycle's diagnostic connector to the AP58 connection instructions in TEXA. Do not select by year alone. | Confirm any external power or battery connection requirement in TEXA's vehicle-specific connection instructions. |
| Any model year, including earlier bikes, where TEXA lists AP05 for the exact manufacturer, model and year. | 3151/AP05 Triumph / generic OBD cable | Match the diagnostic connector to the AP05 connection instructions in TEXA. An OBD label alone does not confirm compatibility. | Confirm any external power or battery connection requirement in TEXA's vehicle-specific connection instructions. |
| Manufacturer/model not confirmed, uncertain year, or connector does not match the specified cable. | Confirm before purchasing. | Send a clear photo of the diagnostic connector with the bike's manufacturer, model and year. | Do not assume that a separate battery connection is required or unnecessary. |
This is a general selection guide, not a verified TEXA model-coverage table. Manufacturer/model-year ranges, connector pin counts and cable-specific power requirements have not been verified here against TEXA documents.
