A previous-calibration listing identifies software considered for a bulletin’s updated revision. It does not mean that 89983-48200 itself provides the improvement described by that bulletin. The model years in each bulletin describe its scope rather than establishing exact fitment for every vehicle.
What the calibration controls
The hybrid controller’s general job is to coordinate requests between the engine, motor-generators and other hybrid-system components. In practice, that coordination affects how the vehicle uses engine and electric power during driving. The available records identify this calibration as an earlier version, but do not establish a specific driving behavior or correction unique to it.
