Toyota and Lexus Firmware 302D4100-ii.cuw

Reading the catalog identifier

The filename contains the calibration identifier 302D4100 and the suffix -ii.cuw. No vehicle application, controller name, service bulletin or named software function is associated with this entry in the available catalog details. Its operating behavior and compatibility therefore cannot be identified reliably from the filename alone.
