What the filename identifies
GSL3## identifies the Sienna model-code family, while 3.5 denotes the engine displacement in the catalog label. The sequence V689661-0831089663-08221 distinguishes this firmware record. It should be considered as a complete identifier rather than treated as interchangeable with another file that shares only part of the code.
The MOD suffix labels this file as a modified variant. It does not state what was changed or establish that the modification adds a particular driving or diagnostic feature. The filename alone also does not establish an exact model year or vehicle compatibility.
