Toyota and Lexus Firmware T-0031-16.cuw

T-0031-16.cuw is a Toyota or Lexus automotive firmware file identifier. The identifier alone does not reliably establish which control module it belongs to or what vehicle function its software controls.

The complete identifier, including the .cuw extension, distinguishes this catalog entry from similarly named firmware files. No specific vehicle application or revision change can be attributed to it from the identifier alone.
