What the filename identifies

The _MOD suffix identifies this file as a modified variant. The filename does not describe the modification, so it does not establish which settings or operating behaviors have changed. The related catalog entry, 89663-60652, provides the base identifier but does not name a vehicle or controller application.

The identifier alone does not establish vehicle compatibility or a specific software revision history.
