How to Remove the Malfunction Indicator Light?

Methods to remove the malfunction indicator light: When the malfunction light is on, start and turn off the vehicle three times in a row, or you can disconnect the negative terminal of the engine battery, wait for 30 seconds, and then reconnect it. When the engine malfunction light is on, it cannot be manually reset. Usually, you need to go to a 4S shop and use a fault diagnostic tool to troubleshoot before it can be reset. This trick only applies to false engine fault phenomena. If it doesn't work, you need to go to a professional repair shop for inspection and reset. If the malfunction light is on but there are no abnormal driving conditions, this may just be a sensor malfunction. In this case, you can continue driving temporarily, but it is recommended to drive at low to medium speeds and immediately go to an auto repair shop for inspection and repair.
Last time the warning light came on in my car, I got pretty nervous at first and quickly pulled over to check if the fuel cap was tightened, because sometimes it being loose can cause the light to come on. If that didn’t work, I used an OBD scanner connected to the car’s port to read the codes, which can tell you the specific issue, like a faulty oxygen sensor or problems with the emission system. Before trying to fix it yourself, it’s best to check the manual or look up the code meanings online. I’ve encountered situations where aging wiring caused poor contact and made the light flicker randomly. In the end, I went to a repair shop and let the professionals handle it—they reset the system, and the light went off. Remember, don’t just clear the codes without fixing the issue, or the problem will persist, leading to higher fuel consumption or engine damage. Taking the time to do these things can save you a lot of trouble. I’ve saved quite a bit of money by doing things myself, but if you’re inexperienced, calling a tow truck is safer. This experience taught me the importance of regular car maintenance checks.
