Toyota Lexus Firmware 34218100-T02ii.cuw

34218100-T02ii.cuw is a Toyota or Lexus firmware catalog identifier. The complete filename identifies this entry, but it does not reliably establish the control module, vehicle application, or software function.

The .cuw extension identifies the file format used for this catalog entry. The T02ii suffix is part of the full identifier and should be retained when distinguishing it from similarly numbered files. It does not, by itself, establish a stock or modified variant or describe a change in vehicle behavior.
