Toyota Yaris D-4D Firmware 1037363755.bin
Toyota Yaris P10 1.4 D-4D engine ECU firmware for Bosch EDC15C9, with identifiers 0281010768 and 89661-52250.
1037363755.bin is cataloged as engine-control firmware for the Bosch EDC15C9 diesel ECU in a Toyota Yaris P10 1.4 D-4D. The entry identifies the engine as the 1ND-TV, rated at 55 kW or 75 PS, and associates the file with Bosch number 0281010768 and Toyota ECU part number 89661-52250.
What the EDC15C9 controls
The EDC15C9 is an electronic diesel engine controller. It uses operating information such as engine speed, temperature and accelerator demand to manage fuel injection. Its calibration determines how the engine responds across operating conditions, influencing starting, throttle response, power delivery, fuel consumption and emissions.
On the Yaris 1.4 D-4D, this role is distinct from a body, transmission or infotainment module. The catalog identifiers point to the diesel engine ECU assembly and its associated software file. They do not, by themselves, establish a particular change made in this calibration revision.
Identifying this catalog entry
The filename combines the vehicle, engine, output, controller family and three identifiers: 0281010768, 89661-52250 and 1037363755. The related catalog entry also lists 89661-52250, reinforcing the Toyota ECU part-number association. The complete set is more useful for distinguishing the record than the EDC15C9 family name alone, since that controller family appears in different diesel applications.
No stock or modified variant label is included in the catalog name, and no specific feature such as an emissions-system change or power increase is identified. The file should therefore be understood as a cataloged engine ECU firmware image, not evidence of a particular modification.
