Toyota 89663-60A32 Firmware: Calibration Reference

89663-60A32 is a Toyota calibration identifier associated with an electronic control module. The 89663 part-number family is generally used for engine control software calibrations, making an engine-control application plausible for this entry.

The exact module, vehicle application and software behavior cannot be established from the identifier alone. An engine-control calibration generally governs functions such as fuel delivery, ignition timing and emissions control, but those general responsibilities do not establish what the 60A32 revision changed.
