How to reset Lexus maintenance fuel injector?

Lexus usually maintains the fuel injector every 10000 km, but if the actual mileage is less than 10000 km (for example, 9000 km), the fuel injector maintenance light set by the computer does not appear on the dashboard, but the vehicle has been maintained normally and fuel injector cleaning agent has been added.

When driving to 10000 km, or driving more than 5000 km when the air-fuel ratio learning value is 20%, the prompt "Fuel injector needs maintenance" will appear on the dashboard, and the triangle warning light will light up. The following are the steps to reset the prompt information for different models.
