Toyota and Lexus Firmware T-0039-12.cuw

T-0039-12.cuw is a Toyota or Lexus automotive firmware catalog identifier. The identifier alone does not establish which control module or vehicle system it belongs to, or what its software controls.

It should be treated as a distinct catalog entry rather than associated with another calibration based on a similar prefix. Vehicle application, controller function and any changes made by this revision are not established by the identifier itself.
