Avensis diesel catalog entries
The files Avensis 2.0D 1ADFTV 89663-05775.bin and Avensis 2.2D 2ADFHV 89663-05775.bin associate the same identifier with the 2.0-liter 1AD-FTV and 2.2-liter 2AD-FHV diesel engines. A third file, 89663-05775.bin, carries the identifier without a vehicle or engine label.
In practical terms, the engine controller uses its calibration to govern how the diesel engine responds to operating conditions, including how fuel is delivered. The catalog names do not identify a specific change made by this revision, and their shared identifier does not establish that the files are interchangeable between the two engines.
