Toyota Firmware 55351100_35366100-ii.cuw

55351100_35366100-ii.cuw is a Toyota or Lexus firmware catalog identifier. The complete filename provides a way to distinguish this entry from other calibration files, but it does not reliably establish the control module, vehicle application, or software function on its own.

The two numeric groups, 55351100 and 35366100, are part of the identifier. A match to a similar prefix alone is not enough to establish that another firmware record serves the same vehicle system or performs the same function.
