Working at a Toyota factory, we change parts a lot for eci. That the general public may not even ever know about. The different manuals could be as simple as changing one word, to changing a supplier of the manuals, to shipping and various things. Any little change, manufacturer/supplier, anything is all documented and considered a part eci. Nothing to be concerned about or worried about. Happens constantlyThat’s interesting Toyota is offering different manuals for the 2021 based on date range. I wonder what changed between the 4 different versions?
