A catalog reference for Toyota firmware identifier 30K87300-ii(4WDAT).cuw and its 4WD automatic-transmission label.
30K87300-ii(4WDAT).cuw is a Toyota firmware catalog filename whose 4WDAT label points to a four-wheel-drive, automatic-transmission configuration. The complete identifier does not reliably establish the control module, vehicle model, or software function.
What the filename identifies
The filename combines the calibration-style identifier 30K87300, the suffix ii, and the configuration label 4WDAT. That label describes the drivetrain configuration associated with this file. It does not, by itself, establish whether the software controls the engine, transmission, four-wheel-drive system, or another module.
The ii suffix is part of the catalog name, but its meaning and any changes associated with this revision are not established by the filename alone. No stock or modified behavior is identified in the name.
