How to eliminate the code on the car?
2 Answers
If the car displays a code fault warning, it is recommended to go to a 4S shop for handling and elimination. This fault code indicates that the car's anti-theft system has been activated, and the car cannot be ignited. If an attempt is made to ignite, the car will be locked. The car anti-theft system refers to a system that prevents the car itself or items on the car from being stolen. Its components include an electronically controlled remote or key, an electronic control circuit, an alarm device, and an actuator. The code system adds electronic identification to the car's locks, generally equipped with remote control technology, which is a more advanced anti-theft technology with functions such as anti-theft alarm, door open warning, and car-finding.
Last time my car also had a yellow warning light, and I spent a long time tinkering with it before fixing it. Actually, clearing fault codes is quite simple for most car models: turn off the engine, disconnect the negative terminal, wait 10 minutes, then reconnect it, and the computer will automatically reboot. If the light is still on, there's probably a real issue. In my case, the light came back after clearing, and it turned out to be a faulty oxygen sensor. It’s most convenient to keep an OBD scanner handy—just plug the几十-dollar device into the port under the steering wheel, and a phone app can read specific fault codes. Codes like P0420 for catalytic converter issues might be drivable, but something like P0301 for a misfiring cylinder—don’t push your luck!
