Toyota and Lexus Firmware T-0020-15.cuw

T-0020-15.cuw is a Toyota or Lexus automotive firmware file identifier. The filename alone does not reliably establish its control module, vehicle application, or the software function it controls.

The complete identifier distinguishes this entry from files with similar prefixes. A controller name, calibration number, part number, or applicable service bulletin would be needed to identify its role more specifically.
