Toyota and Lexus Firmware T-0023-16.cuw

T-0023-16.cuw is a firmware file identifier associated with a Toyota or Lexus catalog entry. The identifier alone does not reliably establish which control module or vehicle system it belongs to, or what the software controls.

No related calibration identifier, controller part number, variant label, or service bulletin is available to distinguish its application. The filename therefore does not establish vehicle fitment or a specific change in behavior.
