This resource provides a special license certificate file that extends the operational life of your offline Caterpillar Service Information System (CAT SIS) until the year 2035. This is an essential file for any technician who relies on an offline installation of CAT SIS for diagnostics and repairs in locations without reliable internet access.

What is Caterpillar SIS?

Caterpillar SIS is the official electronic service tool used by dealers and technicians for all CAT products. It contains a massive library of parts catalogs, repair and maintenance manuals, wiring diagrams, and diagnostic information for the full range of Caterpillar machinery, from 1977 to today.

What Problem Does This Certificate Solve?

Offline installations of Caterpillar SIS typically rely on a license or certificate file that has an expiration date. Once this date passes, the software may stop working or lose its full functionality. This special certificate file replaces the standard license, pushing the expiration date to the year 2035 and effectively providing a lifetime activation for your current installation.
