Toyota and Lexus Firmware T-0028-05.cuw

T-0028-05.cuw is a firmware file identifier associated with a Toyota or Lexus catalog entry. The identifier alone does not reliably establish its control module, vehicle application, or software function.

The complete filename is useful for distinguishing this record from similarly named firmware. It should not be treated as evidence of a particular vehicle fitment or calibration change without a matching service record or controller identification.
