Toyota and Lexus Firmware 899835001400-ii.cuw

899835001400-ii.cuw is a Toyota or Lexus firmware catalog identifier. The complete filename distinguishes this entry from other calibration files, but the identifier alone does not reliably establish its control module, vehicle application, or software function.

The .cuw file extension identifies the entry as a firmware file. The -ii suffix is part of this catalog filename, but it does not by itself establish a stock or modified feature.
