What the identifier tells you
The complete identifier distinguishes this calibration from other entries in the same number family. It does not, by itself, establish which engine, vehicle, or control module it is intended for, or whether a particular revision changes drivability, emissions behavior, or another function.
For a specific vehicle, the calibration ID should be considered alongside the vehicle identification number, control module identification, and applicable Toyota service information. The general role of the 89663 family is not evidence of a particular software change in 89663-F0Z60.
