Toyota and Lexus Firmware 3YWF6301-30CG1001.cuw

3YWF6301-30CG1001.cuw is a Toyota or Lexus automotive firmware catalog identifier. The complete filename identifies this 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 rather than the vehicle system it controls. A matching calibration record or service bulletin would be needed to connect the full identifier to a particular controller and its documented behavior.
