Toyota and Lexus T-0017-08.cuw Firmware Catalog Reference

T-0017-08.cuw is a Toyota or Lexus firmware file identifier. The complete identifier does not reliably establish which control module or vehicle system it belongs to, or what the software controls.

The file name alone does not identify a vehicle application, a stock or modified variant, or a revision-specific change. It should be distinguished from similarly named calibration files rather than matched by prefix alone.
