Toyota and Lexus Firmware 30CF0100-ii.cuw

30CF0100-ii.cuw is a Toyota or Lexus firmware catalog identifier. The calibration code is 30CF0100, and the complete filename includes the -ii.cuw suffix.

The identifier alone does not reliably establish which control module or vehicle system the file belongs to, or what its software controls. A similar calibration prefix is not enough to identify its function or vehicle application.

Catalog identification

Keep the complete filename when comparing this entry with a vehicle’s service record or a controller calibration listing. The code does not, by itself, establish a stock or modified variant, a specific revision change, or compatibility with a particular model.
