Toyota Prius Firmware 89983-47607
A catalog reference for Toyota Prius calibration 89983-47607 and its 2019 service bulletin record.
89983-47607 is a Toyota calibration identifier associated with a Prius service bulletin. The full calibration ID, 899834760700, appears as an updated calibration in Toyota bulletin T-TCI-5019, released November 7, 2019.
Prius service record
The bulletin covers 2016 through 2019 Toyota Prius models. That model range describes the bulletin’s scope, rather than confirming that this calibration applies to every vehicle in it.
The available record does not identify the control module or the condition addressed by the bulletin. It therefore does not establish what vehicle function this revision changes or how it affects driving. The full calibration ID and the bulletin are the useful identifiers for distinguishing this entry from similarly numbered firmware.
