What the catalog identifier describes
The related catalog entry is 89663-52D40, matching the base identifier in the firmware filename. The complete number matters when distinguishing this calibration from other Toyota engine software in the same part-number family.
The catalog does not name a modified variant or identify a specific change made by this revision. The engine control functions described above are the controller family’s general role, not a claim that this file alters a particular driving behavior or corrects a documented fault.
For identification, the vehicle and engine description provides useful context, but the calibration number alone does not establish compatibility with every Ractis 1.5 or every 1NZ-FE engine control module.
