What the MOD label means
The _MOD suffix identifies this filename as a modified variant. The catalog entry does not specify what was modified or how the file differs from a stock calibration. The related identifier 89663-0T220 provides the base calibration reference, but it does not by itself confirm vehicle compatibility or the behavior of the modified file.
