What the engine controller does

The engine control module manages gasoline-engine functions such as fuel injection, ignition timing and electronic throttle operation. In a Prius, it also works with the hybrid control system so the engine can start, stop and produce power as requested. That coordination affects how the car combines engine and electric-motor power during driving.

The exact calibration identifier is 89663-47282, and the associated file is named 89663-47282.bin. The catalog does not name a modified variant or identify a particular change introduced by this calibration. Its identifier should therefore be treated as a specific catalog record, not as evidence of a performance modification or a particular service update.
