The ET 2024 v1.1 software replaces all the previous versions of CAT ET with stability, new driver support futures, and a smoother performance with Windows 11. The Caterpillar program can help technicians diagnose existing and potential problems with their electronically controlled Caterpillar Engines and Machines.
