Toyota Land Cruiser LC200 4.5D Firmware 89663-60V31
A catalog reference for Toyota Land Cruiser LC200 4.5D engine calibration 89663-60V31 and its engine-control role.
89663-60V31 is an engine-control calibration identifier associated in this catalog with the Toyota Land Cruiser LC200 4.5D. The corresponding file is named LC200 4.5D 89663-60V31.bin.
The 89663 part-number family identifies Toyota engine control software. In a diesel vehicle, the engine control module uses its calibration to manage functions such as fuel injection and other engine operating parameters. These controls affect how the engine responds to the accelerator and operates under changing load and temperature conditions.
What the catalog entry identifies
The filename combines the LC200 vehicle designation, a 4.5D diesel description and the full calibration identifier 89663-60V31. It does not name a modified variant or a specific feature change. The engine-control functions described here are the controller’s general role, not a claim that this particular revision introduced a performance or drivability change.
The related catalog entry repeats 89663-60V31 without adding a controller variant or service-bulletin history. The full identifier is therefore the most useful detail for distinguishing this calibration from other Toyota engine software records.
