What the calibration controls
The hybrid vehicle control system coordinates the gasoline engine and electric drive components to meet the driver’s power demand. Its software manages how those systems work together during driving, including transitions between engine and electric operation. The calibration is part of that control strategy, rather than a standalone feature named in the catalog.
Toyota bulletin EG030-07 lists 899834810400 as an updated calibration within its scope for the 2006 and 2007 Highlander HV.
