Toyota and Lexus Firmware T-0023-07.cuw

T-0023-07.cuw is a Toyota or Lexus firmware file identifier. The identifier alone does not reliably establish which control module or vehicle system the file belongs to, or what its software controls.

The complete filename distinguishes this catalog entry from similarly numbered firmware records. A calibration identifier, associated part number, controller name or vehicle-specific service record would be needed to identify its application.
