Toyota and Lexus Firmware T-0065-13.cuw

T-0065-13.cuw is a firmware file identifier associated with a Toyota or Lexus catalog entry. The identifier alone does not reliably establish the control module, vehicle application, or software function.

The complete filename distinguishes this entry from similarly numbered files. A matching calibration record or service bulletin would be needed to identify what the software controls and whether it represents a stock or modified variant.
