The second Lexus LS (UCF20) 1994-2000 refined the flagship formula with a smoother 4.0-litre V8, improved aerodynamics and richer cabin technology. Its expanded electronics make a deliberate reset essential whenever maintenance is carried out. An oil service reset returns the maintenance reminder to zero after the sump is refreshed, while a separate inspection reset handles the longer schedule. Fitting new brake pads calls for the brake pad wear reset, and replacing the battery means a battery reset so the engine management relearns its baselines. Should the one-touch windows stop working, electric window initialization brings them back, and the steering angle sensor can be recalibrated after alignment. Use the menu below to choose the service reset that suits your LS.
