Toyota and Lexus Firmware T-0031-06.cuw

T-0031-06.cuw is a Toyota or Lexus automotive firmware file identifier. Its complete name identifies the catalog entry, but it does not reliably establish the control module, vehicle application or software function.

The .cuw extension identifies the file format. A matching filename prefix alone is not enough to associate this entry with a particular controller or vehicle system. No stock or modified variant label is available for this identifier.
