Toyota and Lexus Firmware T-0049-09.cuw

T-0049-09.cuw is a firmware file identifier associated with Toyota or Lexus automotive software. The complete filename identifies this catalog entry, but it does not establish the vehicle application, control module, or software function on its own.

The .cuw extension and the identifier should be retained exactly when comparing service or catalog records. A similar prefix alone is not enough to establish that another file belongs to the same controller or performs the same function.
