Toyota and Lexus Firmware T-0028-17.cuw

T-0028-17.cuw is a Toyota or Lexus firmware file identifier. The complete identifier distinguishes this entry from files with a similar prefix, but it does not by itself establish the control module, vehicle application or software function.

The .cuw filename and calibration identifier are useful for catalog identification. A matching controller or vehicle record is needed to determine what the firmware controls and whether a particular revision addresses a documented operating concern.
