Catalog identification
The entries 89663-52F83.bin and 89663-52F83.rar carry the same complete identifier. The first is named as a binary file and the second as a compressed archive. Neither filename identifies a stock or modified variant or names a specific vehicle or feature.
For diagnostic or catalog matching, the full identifier matters. A similar-looking calibration number is not sufficient to establish that software is interchangeable with 89663-52F83.
