Toyota and Lexus Firmware L-0005-09.cuw

L-0005-09.cuw is a firmware file identifier associated with Toyota or Lexus vehicle software. The complete code identifies this catalog entry, but it does not reliably establish the control module, vehicle application or software function on its own.

The .cuw extension identifies the file format in the catalog name. It does not by itself establish whether the file is a stock calibration or a modified variant, or describe a change in vehicle behavior.
