Toyota 896655301100 (1).bin Firmware

896655301100 (1).bin is a Toyota firmware catalog filename in the 89665 electronic control unit part-number family. That family is commonly associated with engine control modules, which manage functions such as fuel injection and ignition timing using engine operating data.

The engine-control association is tentative for this complete identifier. The filename alone does not establish the vehicle application, the calibration’s specific behavior, or whether the file is a stock or modified variant. The (1) suffix is part of the catalog filename and does not by itself describe a software feature.
