Toyota and Lexus Firmware T-0059-12.cuw

T-0059-12.cuw is a Toyota or Lexus automotive firmware catalog identifier. The identifier alone does not establish which control module it belongs to or what vehicle function its software controls.

The complete filename distinguishes this entry from similarly numbered firmware records. A controller description, part number, vehicle application, or associated service bulletin would be needed to identify its function and determine whether it is a stock or modified variant.
