Those controls affect how the engine responds to the accelerator and runs under changing loads. This describes the controller family’s general role, not a documented change made by 89663-60A02.
The catalog filename Land Cruiser Prado 120 3.0D 89663-60A02.bin identifies a binary firmware file and associates it with the Prado 120 diesel application. It does not name a modified variant or describe a specific change to engine behavior.
