89663-42642 is a Toyota engine-control calibration identifier cataloged for a RAV4 with the 3.5-liter 2GR-FE V6 and four-wheel drive. It belongs to the Toyota engine control module software family, which manages engine operation using sensor inputs and programmed control strategies.

Engine-control role
