Toyota and Lexus Firmware 55021100-L04ii.cuw

55021100-L04ii.cuw is a firmware file identifier associated with a Toyota or Lexus catalog entry. The complete identifier distinguishes it from files with a similar numeric prefix or a different suffix.

The identifier alone does not reliably establish the control module, vehicle application, or software function. It also does not identify a stock or modified variant, or describe a change made by this revision.
