What is the method to reset the IS250 fuel injector maintenance light?
2 Answers
Start the vehicle, use the menu button on the right side of the multifunction steering wheel to access the vehicle driving information on the central control screen, then adjust the display information. Press the mode button on the steering wheel, and observe the vehicle's dashboard; the fuel injector maintenance information will be reset. More details are as follows: 1. The IS250 is a model under the Lexus brand. Lexus is a luxury car brand from the Toyota Group of Japan, established in 1983 with its headquarters in Tokyo, Japan. It was initially launched in North America and successfully entered the Japanese domestic market in 2005, achieving excellent results. 2. Currently, all Lexus models sold are imported versions. Therefore, the Lexus brand belongs to Toyota Motor Corporation of Japan. Toyota also has two divisions in China, but neither produces Lexus brand models. Those waiting for domestically produced models will need to continue to follow updates.
As a young person who frequently tinkers with my own car, let me tell you, the IS250 fuel injector maintenance light is no small matter. When the light comes on, it indicates potential clogging or carbon buildup in the engine warning system. First, you need to check if the fuel injectors are dirty. The reset method is simple: turn the key to the ON position without starting the engine, then locate the menu button on the steering wheel, enter the system settings, select the maintenance reset option, and hold the OK button for a few seconds until the light goes off. Never tamper with the wiring or use random tools found online—I tried that once and nearly damaged the ECU. Cleaning the fuel injectors can prevent this light from coming on; just add a bottle of fuel additive every three months. Regular maintenance of engine oil and air filters can also reduce clogging. After the light is reset, take the car for a high-speed test drive to ensure everything is working properly. In short, DIY is fun, but don’t mess around—safety first. The key to saving on maintenance costs is to read the manual thoroughly before getting started.
