A catalog reference for Toyota and Lexus firmware file FJ-2009-3YWK0300-=3546000.cuw and its identifying codes.
FJ-2009-3YWK0300-=3546000.cuw is a firmware catalog identifier associated with Toyota or Lexus vehicles. Its identifying elements include FJ-2009, the calibration-like code 3YWK0300, and the number 3546000.
The complete filename does not reliably establish a control module, vehicle system, or software function. In particular, it should not be assigned to a similarly named calibration solely because part of the identifier matches.
Using the identifier
The full filename is useful for distinguishing this record from other firmware entries. It does not, by itself, establish vehicle fitment, a stock or modified variant, or a change in vehicle behavior.
