Toyota and Lexus Firmware T-0124-12.cuw

T-0124-12.cuw is a Toyota or Lexus firmware identifier. The complete identifier distinguishes this catalog entry from similarly named files, but it does not reliably establish which control module or vehicle system the firmware belongs to.

The identifier alone also does not establish a vehicle application, software function or revision change. A matching controller record or service bulletin would be needed to identify those details.
