Toyota Prius Firmware 89663-47110
A catalog reference for Toyota Prius 1.5-liter hybrid firmware 89663-47110 and its engine control calibration family.
Toyota firmware 89663-47110 is cataloged for a Prius 1.5-liter hybrid with the 1NZ-FXE engine. The 89663 part-number family is associated with engine control software, so this entry is best understood as an engine ECU calibration for that hybrid application.
The engine control ECU manages functions such as fuel injection and ignition timing, working with the hybrid control system as the gasoline engine starts, stops and supplies power. The catalog name identifies the engine and calibration, but it does not establish the specific changes made by this software revision.
Catalog variants
The filenames Prius 1.5hyb 1NZFXE 89663-47110.bin and 89663-47110.bin carry the same calibration identifier. A third entry, 89663-47110-A, adds an A suffix but does not name a modified feature or explain how it differs.
The Prius model year, ECU hardware compatibility and any revision-specific behavior are not identified by these filenames alone.
