Reading the filename
Sequoia_USK6###_5.7 describes the vehicle and engine family associated with the entry. V889661-0CC8189663-0CA21 is the identifier carried by this file and should be considered as a complete string when distinguishing it from other Sequoia firmware records. The MOD suffix denotes a modified variant rather than a stock-labeled file.
The filename does not name a specific driving function or describe the difference between this modified variant and any stock calibration. It therefore cannot establish a particular effect on engine operation, transmission behavior, emissions controls, or another vehicle system.
