Toyota and Lexus Firmware T-0086-14.cuw

T-0086-14.cuw is a Toyota or Lexus firmware catalog identifier. The identifier alone does not reliably establish which control module or vehicle system it belongs to, or what its software controls.

The complete filename is useful for distinguishing this entry from similarly numbered firmware records. A vehicle application, calibration identifier, part number or service bulletin would be needed to identify its specific function.
