How to reset the engine warning light on BYD F3?

[Santos]

Try starting and turning off the vehicle three times in a row, or disconnect the negative terminal of the engine battery, wait for 30 seconds, reconnect it, and then attempt to start the vehicle. If the issue persists, it is usually necessary to visit a 4S dealership to use a fault diagnostic tool for troubleshooting before the warning light can be reset. The engine warning light may be triggered by the following reasons: 1. Sensor issues. The sensors mentioned here include those for coolant temperature, crankshaft position, air flow, intake air temperature, oxygen, etc. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, which will cause the engine warning light to illuminate. 2. Maintenance issues. Poor engine maintenance is the most common cause of the engine warning light. Vehicles have specific maintenance cycles. If the owner does not adhere to the maintenance schedule and combines it with poor driving habits, the engine's operational burden will increase, ultimately triggering the warning light as a reminder. 3. Fuel and oil quality issues. The quality of fuel and engine oil is crucial here. The fuel used in cars generally has a specific grade, and engine oil can be semi-synthetic or fully synthetic. Manufacturers usually recommend which fuel grade and type of engine oil to use. If the owner does not follow these recommendations, long-term use can lead to engine wear.
