Engine-control context
The engine control module manages diesel engine operation, including fuel injection, using sensor information and programmed calibration values. Its software helps determine how the engine responds to driving demands and operates across different conditions.
The catalog filename, Avensis 2.0 D4D 1ADFTV 89663-05552.bin, identifies the vehicle and engine but does not name a particular software change or modified feature. It therefore supports an engine-control context, not a specific claim about what this revision changes.
