89663-02Q91.bin is a Toyota firmware catalog entry identified by the calibration number 89663-02Q91. The related catalog name repeats the same identifier and does not name a vehicle, controller or software variant.
What the identifier indicates
The 89663 number family is associated with Toyota electronic control software calibrations. The complete identifier is important because the shared prefix alone does not establish which control function or vehicle application this particular file belongs to.
