You are welcome! Glad you found it useful.

Just a heads up regarding Cat ET 2019C: make sure your Comm Adapter 3 (CA3) firmware is up to date. This version can be a little picky with older drivers, especially on Windows 10.

If you run into connection issues where it can't find the ECM, double-check your adapter settings here:

Code: 
Utilities -> Preferences -> Modify -> Communications

Let us know if the installation goes smoothly!

Great news! Thanks for the update.

Since it's a fresh install, I'd suggest running a Product Status Report (PSR) on the first machine you connect to. It's a good way to double-check that the reporting function is generating PDFs correctly, as sometimes the PDF printer settings can be a bit finicky on new setups.

Happy diagnosing!
 
¿Tendrás una versión más reciente, 2023 o 2024?, necesito diagnosticar un cargador frontal Caterpillar 2019 con sistema def y el et cat 2019c no me deja ver todos los sistemas.Muchas gracias.

Sí, existen versiones más recientes como la 2023C y la 2024A.

Para maquinaria moderna (especialmente motores Tier 4 Final y Stage V), definitivamente necesitas actualizarte, ya que la 2019C no leerá los archivos flash más nuevos ni reconocerá ciertos ECMs recientes.

Solo ten cuidado con dos cosas al actualizar a 2023/2024:
  • Los requisitos de activación son diferentes (a menudo requieren conexión a servidor o parches más complejos).
  • Algunos adaptadores clones antiguos del CA3 pueden dejar de funcionar o pedir actualizaciones de firmware que podrían bloquearlos.

Te recomiendo usar el buscador del foro para encontrar los hilos específicos de la versión 2023A o 2024A, ya que suelen publicarse por separado debido a los cambios en la licencia.

No problem, boss! Glad I could help.

If you manage to find a newer version and need advice on installation or compatibility, don't hesitate to ask. Sometimes these newer versions have specific quirks with certain operating systems or adapters. Happy to share any insights we might have.

You're very welcome!

Good luck with that loader. Just a quick tip for the DEF system once you get the right software version connected: keep an eye on the Aftertreatment Regeneration History and run the SCR System Functional Test if available.

Those are usually the best places to start when troubleshooting AdBlue/DEF quality or pump pressure issues on the newer Tier 4 machines. Let us know how you get on!
