Toyota and Lexus Firmware 54825000-L04ii.cuw

54825000-L04ii.cuw is a Toyota or Lexus firmware catalog identifier. The complete identifier distinguishes this file from other calibration records, but it does not establish the control module or vehicle system it belongs to.

The .cuw filename and the 54825000-L04ii identifier should be retained together when comparing catalog or service records. A similar prefix alone is not enough to identify the file’s function, vehicle application, or the changes made by this revision.
