Toyota and Lexus Firmware T-0025-13.cuw

T-0025-13.cuw is a Toyota or Lexus firmware catalog identifier. The identifier alone does not reliably establish which control module it belongs to or what vehicle function its software controls.

Identifying the application

The complete filename is important when distinguishing this entry from similarly numbered firmware. A controller name, calibration identifier, part number or service bulletin would be needed to connect T-0025-13.cuw to a specific vehicle system or software revision.
