Reading the identifier
The vehicle and drivetrain labels distinguish this entry from other Tundra firmware records. 30CJ6401 is the specific calibration identifier within the filename. A match to a similar identifier alone is not enough to establish the controller application or the changes in this revision.
No stock or modified variant is named in this filename. Its four-wheel-drive label identifies the catalog context, but it does not by itself show that the software controls the transfer case or another particular drivetrain component.
