Toyota Firmware 89663-22163: Engine Control Calibration
A catalog reference for Toyota firmware 89663-22163 and its likely engine control module family.
89663-22163 is a Toyota calibration identifier in a part-number family associated with engine control module software. Its association with an engine control module is tentative for this exact identifier.
