CAT ET Software

CAT ET Software

Caterpillar Electronic Technician (Cat ET Software) is diagnostic software used by Caterpillar dealers.  It’s required to communicate, diagnose and service electronically controlled Caterpillar engines and machines. When connected to an ECM, a technician has the ability to diagnose existing and potential problems, configure the product, and obtain data for analysis.  If you’re working on Caterpillar engines, this is diagnostic software you are going to be using.  Caterpillar Electronic Technician has all of the tools and capabilities you’ll need to diagnose and repair your CAT engines.
