We found the older CAT ET SIS 2019 version quite frankly a little buggy. The Caterpillar SIS parts searches were either painfully slow or CAT SIS would just hang, freeze be brutally slow! And in some cases you would get the dreaded CAT ET SIS license has expired or “Not allowed to connect to an ECM on the data link. This program is not licensed.”
