Toyota and Lexus Firmware 896653002100 (2).bin

896653002100 (2).bin is a firmware filename associated with a Toyota or Lexus electronic control module part-number family. The identifier begins with 89665, a prefix commonly associated with engine control computers, but the complete identifier and filename do not establish a specific vehicle or control function.

An engine control computer generally manages fuel delivery and ignition using sensor inputs to regulate engine operation. That general role should not be taken as proof that this particular file controls those functions or introduces a specific change. The (2) suffix is part of the filename and does not, by itself, identify a stock or modified variant.
