What the engine controller does
A diesel ECU uses inputs such as engine speed, temperature and accelerator demand to determine fuel delivery. It also coordinates engine-management functions associated with emissions and fault monitoring. These are general roles of the EDC17 controller family, not a description of a specific change made by calibration 1037506310.
The filename combines the vehicle and engine description with the controller designation, calibration identifier and Toyota part-number family 89663-02L02. Together, these details distinguish the record from other Auris and EDC17 firmware entries. The related catalog entry repeats 89663-02L02 but does not name a separate stock or modified variant.
Diagnostic context
When investigating an engine-management issue, the ECU's identification details help distinguish the software fitted to a vehicle from another calibration in the same controller family. The catalog filename alone does not establish a particular fault correction, emissions modification or compatibility with every Auris 1.4 diesel.
