What the catalog identifies

The filename Yaris 1.3 2SZFE 89663-0D140.bin identifies the vehicle, engine and calibration together. This association is useful when distinguishing the entry from other Toyota firmware records, though the filename alone does not establish fitment for every Yaris 1.3.

A second catalog entry, 89663-0D140-B, carries the same base identifier with a B suffix. The label does not state whether it is a stock revision or a modified variant, or identify a particular change in engine behavior.

The catalog does not describe a fault correction or performance change specific to 89663-0D140. Its identified role is as part of the engine-control software for the named application, rather than a documented update for a particular driving symptom.
