Toyota and Lexus Firmware 30439300-ii.bin

30439300-ii.bin is a binary firmware filename associated with a Toyota or Lexus catalog entry. The complete identifier distinguishes it from files with similar numeric prefixes.

The filename alone does not reliably identify the control module, vehicle application or software function. The -ii suffix is part of the catalog filename, but its meaning as a stock or modified variant is not established by the identifier itself.
