What the engine firmware controls
The engine control module uses its software and calibration data to manage diesel fuel injection in response to operating conditions. This affects how the engine starts, responds to the accelerator and runs under load. The controller also coordinates other engine-management functions according to the vehicle’s equipment.
The catalog identifies this file by vehicle, engine and calibration code. It does not name a modified variant or a specific change made by this revision. The identifier is therefore useful for distinguishing the record, but it does not by itself establish compatibility with every Hilux 2KD-FTV configuration.
