Toyota and Lexus Firmware 30439100-ii.cuw

30439100-ii.cuw is a Toyota or Lexus firmware catalog identifier. The complete filename identifies the entry, but it does not reliably establish the control module, vehicle application, or software function.

The .cuw extension identifies the file format, while 30439100-ii distinguishes this record from other firmware entries. It should not be matched to a vehicle or controller solely because another identifier begins with similar digits.
