Toyota and Lexus Firmware T-0028-10.cuw

T-0028-10.cuw is a Toyota or Lexus firmware catalog identifier. The complete identifier does not establish a specific control module, vehicle application, or software function on its own.

The .cuw filename and calibration code can be used to distinguish this entry from other firmware records. A controller designation, related catalog filename, or service bulletin would be needed to associate it reliably with a vehicle system or a documented software change.
