Toyota and Lexus Firmware T-0041-09.cuw

T-0041-09.cuw is a firmware file identifier associated with Toyota or Lexus automotive software. The identifier alone does not reliably establish which control module it belongs to or what vehicle function it controls.

The complete filename distinguishes this entry from other calibration files, but it does not by itself establish vehicle fitment, a stock or modified variant, or a specific software revision.
