Toyota and Lexus Firmware 30KA1200-ii.cuw
Catalog reference for Toyota and Lexus firmware file 30KA1200-ii.cuw and its calibration identifier.
30KA1200-ii.cuw is a Toyota or Lexus automotive firmware catalog identifier. The supplied identifier does not reliably establish which control module or vehicle system it belongs to, so its effect on vehicle operation cannot be determined from the filename alone.
The complete identifier matters when comparing calibration records. The -ii suffix is part of this filename, but the name alone does not establish whether it denotes a stock calibration, a modified variant, or a particular software function.
A matching controller record or Toyota service bulletin would be needed to associate this file with a specific application or documented revision.
