How to eliminate the fault light of BYD F3?

[AaronLynn]

The methods to eliminate the fault light of BYD F3 are: 1. Try to start and turn off the vehicle three times in a row, or turn off the engine and disconnect the negative terminal of the battery, wait for 30 seconds, reconnect it, and then try to start the vehicle; 2. If it still doesn't work, you need to go to a 4S store to use a fault detector to troubleshoot before it can be eliminated. The reasons for the engine light to come on include: 1. Sensor problems; 2. Maintenance issues; 3. Fuel quality problems. The BYD F3 is an A+ class passenger car from BYD Auto, with a body length, width, and height of 4533mm, 1705mm, and 1490mm respectively, a wheelbase of 2600mm, a body weight of 1200 kg, a fuel tank capacity of 50 liters, and a top speed of 170km/h.

Last time my BYD F3's warning light came on, it was quite a headache. I tinkered with it for a long time but couldn't fix it. Generally, when the warning light comes on, it means the system has detected a problem. The most common issues are with the emission system, such as a dirty oxygen sensor, a weak fuel pump, or something as simple as the fuel cap not being tightened properly. You should first plug an OBD scanner into the port under the steering wheel to read the fault codes—you can buy a cheap Bluetooth version online for just a few dozen bucks, which can tell you which part is faulty. If you find a problem, you can handle minor tasks yourself, like cleaning the sensor, but for more complex issues, you'll need to take it to a shop. After fixing it, the light might not turn off immediately—drive around for a while to let it self-check, or disconnect the battery's negative terminal for a few seconds to reset it. In short, don't drive it hard; check it thoroughly before hitting the road—safety first. Regular maintenance can help prevent issues.

As a DIY-savvy car owner, when the warning light on my BYD F3 comes on, I immediately pull out an OBD scanner for diagnosis. Identifying the trouble code is crucial—it could indicate engine misfires or sensor malfunctions. After reading the code, I attempt repairs myself, like checking for clogged air filters or worn spark plugs; a simple cleaning might turn off the light. For a quick reset, try disconnecting the battery for a few minutes after turning off the engine, but if the light reappears, the underlying issue persists. Post-repair, take the car for a test drive to let the system relearn; sometimes a highway run makes the light disappear automatically. If repeated attempts fail, don't push it—visit a professional shop for a thorough check to avoid costly damage. Regular maintenance helps prevent such issues.

I encountered warning light issues with my BYD F3, and solving them requires tech tools. I recommend getting an OBD scanner that connects to your phone—just plug it in to read fault codes, easily identifying causes like sensor false alarms or emission faults. After handling minor issues, the light sometimes turns off automatically, or you can reset it with the tool. Don't forget regular maintenance to reduce problems.
