Toyota and Lexus Firmware 896635001100 (1).bin

896635001100 (1).bin is a firmware catalog filename containing the identifier 896635001100. Its format is consistent with a Toyota or Lexus calibration identifier in the 89663 part-number family, which is associated with engine control software.

Engine control family and application

The association with engine control is tentative. An engine control module uses calibration data to manage functions such as fuel delivery, ignition timing and emissions controls, but the identifier alone does not establish which of those functions this file changes.

The filename does not identify a vehicle model, engine or software variant. The (1) suffix can be part of a filename copy and does not by itself establish a modified calibration or a revision history.
