What the identifier establishes
The complete calibration identifier is 89663-48G00. The filename adds the variant label MOD1 iv.bin, but the label alone does not establish what was changed or what “iv” means. It should not be treated as a confirmed description of a particular feature.
The Highlander name identifies the catalog application. The identifier does not establish a specific model year, engine, market or compatible control unit. The engine control module’s general role also does not describe the changes made in this particular modified file.
