What the catalog files identify
The related entries pair 89663-26400 with two K-TAG file extensions: .EPR and .MPC. These represent separately named parts of the controller data, rather than evidence of different driving features. A third entry, 89663-26400-A, adds an A suffix but does not describe a stock or modified function.
The controller’s general role is to use engine operating information to determine fuel delivery and coordinate engine operation. The catalog names do not establish what changed in this particular calibration or whether the A-suffixed entry differs in behavior. The stated Hiace, engine, year and power figure are the application details supplied by the file names, not a complete compatibility list.
