Toyota and Lexus Firmware 30CB0200-ii.cuw

30CB0200-ii.cuw is a firmware catalog identifier associated with Toyota or Lexus. The complete filename identifies this entry, but it does not reliably establish the control module, vehicle application, or software function.

The -ii.cuw suffix is part of the catalog filename. It does not by itself identify a stock or modified variant, a particular feature, or a compatible vehicle. A matching controller record or service bulletin would be needed to establish what this calibration controls.
