Upgrading Old Lexus LS 600h Dashboard to the Newer Model (2017) Version

Installed the instrument cluster from 460 restyling, the panel was from a gasoline model with rear-wheel drive and right steering wheel. After installation, the speedometer reset itself, showing speeds up to 280 km/h, and the language immediately switched to Russian. Upon rebooting, the hybrid scale appeared! The only downside is that the speedometer cannot display fuel consumption, and as a result, the entire car stopped showing range and average consumption.
