Sequoia_USK6###_5.7_V889661-0CJ3089663-YWL19-MOD_E2.bin is a Toyota Sequoia 5.7 firmware catalog entry marked as a modified variant. The filename identifies the USK6### vehicle designation and a calibration or file identifier, but it does not establish which control module the file belongs to or what vehicle function the modification changes.

Reading the firmware identifier

MOD_E2 is the variant label in this filename. It distinguishes the entry as modified, but the label alone does not define the modified behavior or establish a comparison with a particular stock file. The remaining string, V889661-0CJ3089663-YWL19, identifies the cataloged file and should be considered in full when matching it to a service record or controller application.

The Sequoia and 5.7 labels provide vehicle and engine context rather than a confirmed module assignment. The filename does not by itself establish a model year, exact fitment, revision history, or the software’s effect on driving.
