A concise reference to the Toyota TUNDRA-30CA3100.cuw firmware identifier and its catalog designation.

Reading the identifier
The TUNDRA label is the vehicle designation in the catalog name. The complete identifier 30CA3100 distinguishes this file from other entries that may share part of its numbering. The .cuw extension identifies the file format, but does not by itself establish the controller or exact vehicle fitment.
No stock or modified variant label is present in the filename. A specific software change or operating behavior cannot be attributed to this revision from the catalog name alone.
