Those controls affect how the engine starts, responds to the accelerator and runs under different conditions.

What the identifiers describe

The file is listed as Auris 1.4D (1NDTV) 1037536735 89663-02T91.bin. The vehicle and engine labels identify its catalog application, while 1037536735 and 89663-02T91 distinguish the firmware record. The related catalog name repeats 89663-02T91.

The catalog does not identify a specific drivability improvement, emissions change or modified variant for this file. Its identifiers are useful for comparing an existing engine-control record, but the Auris label alone does not establish compatibility with every 1.4D vehicle.
