Toyota and Lexus Firmware 32105100-T05ii.cuw

32105100-T05ii.cuw is a firmware catalog identifier associated with Toyota or Lexus automotive software. The complete identifier does not establish a specific control module, vehicle application, or software function on its own.

The .cuw extension identifies the catalog file format, but it does not by itself distinguish an engine, transmission, body, or other vehicle controller. The suffix T05ii is part of the identifier and should be retained when comparing this entry with service or calibration records.

A matching vehicle record, controller designation, or Toyota service bulletin would be needed to describe this calibration’s role or distinguish a stock file from a modified variant.
