Toyota and Lexus Firmware 30CJ6100.cuw

30CJ6100.cuw is a Toyota or Lexus firmware file identifier. The complete code identifies this catalog entry, but it does not establish a specific control module, vehicle application, or software function on its own.

The .cuw extension identifies the file format, not the system it controls. A controller name, related calibration information, or a service record would be needed to associate this file reliably with a vehicle function or a particular revision.
