Toyota and Lexus Firmware 34221100-T02.cuw

34221100-T02.cuw is a Toyota or Lexus firmware catalog identifier. The complete identifier distinguishes this record from other files with similar prefixes, but it does not establish the control module or vehicle system on its own.

The .cuw filename and calibration identifier provide a way to recognize the file in a catalog. A vehicle application, software function or change made by this revision cannot be reliably identified from the filename alone.
