A catalog reference for Toyota Prius V calibration 89663-47581 and its association with the 1.8-liter 2ZR-FXE hybrid powertrain.
Toyota 89663-47581 is cataloged as a firmware calibration for the Prius V with the 1.8-liter 2ZR-FXE engine. The Toyota 89663 part-number family is associated with engine control software, making an engine or powertrain ECU calibration the most likely identification.

This coordination helps determine how the engine contributes to propulsion and battery charging.
What the catalog identifier establishes
The filename Prius V 1.8 2ZRFXE 89663-47581.bin identifies the vehicle family, engine and calibration number. It does not name a modified variant or describe a particular change made by this revision. The engine-control association is therefore best treated as tentative rather than as proof of a specific update or repair.
The complete calibration identifier matters when comparing ECU records. A similar 89663 number can represent a different application or revision, so the shared prefix alone does not establish compatibility.
