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.
