TheYellow is the ECULogicX portal for Caterpillar equipment. It covers ADEM A4 and A5 engine ECMs as well as the C-Series (C4.4, C7.1, C9.3, C13, C15) controllers found in 320–352 excavators, 950–982 wheel loaders, D6–D9 dozers and Cat gensets. Site deadlines don't wait, so most standard files are returned within the hour during support windows.
ADEM A4, ADEM A5 and the C-Series engine controllers. Perkins-built Cat engines (C4.4, C7.1) are included.
We deliver the software; reading and writing is done on site with your tool. Our knowledge base lists read methods per ECM.
