Calibration identifier and application

Toyota part numbers in the 89663 family are associated with electronic control unit software calibrations, commonly for powertrain control. That family association suggests a controller calibration, but it does not establish the exact module, vehicle application or function of 89663-48710.

The (2) suffix distinguishes this filename from another file bearing the same base name. It does not, by itself, identify a stock or modified calibration or describe a change in vehicle behavior.
