Toyota 89663-04B24 Firmware Calibration

89663-04B24 is a Toyota calibration identifier in the 89663 part-number family, which is generally associated with engine control module software. The exact vehicle application and the changes made by this calibration cannot be established from the identifier alone.

Engine control family

An engine control module uses calibration data to manage operating functions such as fuel delivery, ignition timing and emissions controls. These functions affect how the engine responds to driving conditions. The association with engine control is tentative for this specific identifier, and it does not establish what 89663-04B24 changes compared with another calibration.
