The exact vehicle application and the changes represented by this calibration are not established by the catalog filenames alone.
Catalog filenames
The entry appears as 89663-0CA02.bin and 89663-0CA02-.bin. Both contain the same calibration identifier. The trailing hyphen in the second filename does not identify a specific modified function or establish a difference in vehicle compatibility.
The identifier can help distinguish this calibration from other Toyota firmware records, but it is not enough by itself to confirm fitment or a particular software improvement.
