Toyota and Lexus Firmware 30404100-T02ii.cuw

30404100-T02ii.cuw is a firmware file identifier associated with Toyota or Lexus automotive software. The complete identifier distinguishes this catalog entry from files with similar prefixes.

The identifier alone does not reliably establish which control module it belongs to or what vehicle function it controls. A matching vehicle, controller part number or service record would be needed to describe its application or any changes made by this revision.
