Toyota and Lexus Firmware 30553400-ii.cuw

30553400-ii.cuw is a Toyota or Lexus automotive firmware catalog identifier. The complete filename identifies this entry, but it does not establish a specific control module, vehicle application, or software function.

The 30553400 calibration identifier and -ii.cuw filename suffix should be kept together when comparing records. A similar prefix alone is not enough to establish that another firmware file controls the same system or is interchangeable with this one.
