What the catalog filename identifies
The entry appears as 16607.olsToyota Avensis 2.2 D-4Di Denso 89663-05760-A v2_csnone_csnone.bin. It identifies the vehicle and diesel engine, Denso as the controller manufacturer, and the calibration identifier 89663-05760-A. The related catalog entry 89663-05760 shares the base part-number identifier.
The v2 label distinguishes this file in the catalog, while csnone_csnone is part of its filename. These labels do not identify a specific change to injection, emissions control or driving behavior. The filename also does not name a modified function, so it should not be treated as evidence of a performance or emissions modification.
Engine-control context
In normal operation, the diesel engine controller calculates and commands fuel injection according to operating conditions. Its calibration influences how those commands are applied across the engine’s working range. The catalog identifier establishes the association with this Avensis engine-control record, but it does not describe what this particular revision changed or establish compatibility with another vehicle.
