Toyota and Lexus Firmware 54816000-L04ii.cuw

54816000-L04ii.cuw is a Toyota or Lexus automotive firmware catalog identifier. The complete filename distinguishes this entry from other calibration records, but it does not establish a specific control module, vehicle application, or software function on its own.

The suffix L04ii is part of the identifier. Its meaning as a stock or modified variant label cannot be determined reliably from the filename alone.
