What is the method to reset the tire pressure on the BYD Song?

[VonIsla]

BYD Song tire pressure needs to be reset, usually due to the following issues. After resolving these issues, driving a few kilometers will automatically reset the tire pressure. The issues are as follows: First: BYD Song tire pressure monitoring alarm. Tire pressure fault warning light: 1. When the 'Start/Stop' button is in the 'ON' position, this light turns on. If the tire pressure monitoring system is functioning normally, the light will turn off after a few seconds. Subsequently, if a system fault occurs, this light will turn on again. 2. When the tire pressure fault warning light turns on or flashes, and the right-side information display shows 'Please check the tire pressure monitoring system' with the tire pressure display interface showing '---', it indicates a fault in the tire pressure system. 3. When the tire pressure fault warning light flashes rapidly, and one or more values on the right-side information display tire pressure interface turn red, it indicates that the corresponding tire is in a rapid air loss state. 4. When the tire pressure fault warning light remains on, and one or more values on the right-side information display tire pressure interface turn yellow, it indicates that the corresponding tire is in an underinflated state. If any of the above situations occur, it is recommended to contact a BYD authorized service center for vehicle inspection. Second: Underinflated tire pressure alarm. 1. When the tire pressure of all four tires is below 75% of the standard tire pressure value and the system is operational, the tire pressure monitoring system will issue a low-pressure alarm signal within 1 minute and indicate the position of the underinflated tire. 2. After the low-pressure alarm, inflate the tire to the standard pressure. When the tire pressure exceeds 90% of the standard pressure, the low-pressure alarm will be canceled. After resolving the above issues, driving a few kilometers will automatically reset the tire pressure.

I recently dealt with the tire pressure reset issue on my BYD Song. The operation is actually quite simple: first, make sure all four tires are inflated to the standard pressure (the specific values are marked on the door B-pillar or in the manual). Then, start the car without moving it, find the 'Return' button and the menu button with a musical note on the left side of the steering wheel, and press and hold both for about three seconds. The display in the middle of the dashboard will flash the tire pressure symbol, then you can release the buttons. When I helped my neighbor with his older model Song last time, he could even reset it via Bluetooth through the mobile app, which was quite convenient. After resetting, it's best to drive a kilometer or two to let the system re-detect the tire pressure. If the warning light doesn't come back on, then it's all set.

Just helped a friend deal with the tire pressure warning on their new Song PRO yesterday. After starting the vehicle, directly operate the central control screen—swipe down from the top to enter the quick menu, find the car icon, go into 'Vehicle Status,' and there you'll see the 'Tire Pressure Monitoring System.' Hit the 'Calibrate' button, wait about ten seconds, and once the yellow exclamation mark on the dashboard disappears, you're done. One crucial note: always adjust the tire pressure before resetting. In summer, don’t overinflate, as it can trigger false alarms. Once, I forgot to adjust the spare tire’s pressure, and the alarm went off again on the highway—what a hassle.

Last time when the tire pressure warning light came on in my Song PLUS, I figured out a makeshift solution: first turn off the engine but keep the power on without starting it, then press and hold the rectangular 'Confirm' button on the left side of the steering wheel for about five seconds until you hear a beep, and the tire pressure light on the dashboard starts flashing. Then drive slowly for about ten minutes, and the system will automatically learn the new tire pressure data, causing the warning light to turn off. Remember, if frequent alarms occur within a month after resetting, it might be due to mud or water entering the wheel speed sensor or physical impact, and you should visit a 4S shop for a computer diagnostic check.

From my experience, the operation varies slightly across different year models of the Song series. For the 2017 model, there's a hidden SET button inside the glove compartment—press and hold it for three seconds until the red light turns green. For newer models, simply locate the physical button with the tire pressure symbol near the electronic gear shift, hold it until the dashboard flashes, then release. Three key points: reset must be done with cold tires; tire pressures must be absolutely identical (even a 0.1bar difference may cause failure); if the warning light reappears on bumpy roads after reset, it's usually a false alarm—just restart the system. Last time I encountered this on National Highway 318, stopping and restarting the car fixed it.

Three simple steps: Park the car, shift to P gear, and pull the handbrake. Adjust the tire pressure to 2.3-2.5 bar (depending on the model), and turn on the ignition without starting the engine. For new models, enter the new energy menu on the central control screen and select tire pressure calibration. For older models, press and hold the combination buttons on the left side of the steering wheel (return button + volume button) simultaneously. A successful reset will be indicated by the flashing and then extinguishing of the tire pressure warning light. Important notes: Reset is mandatory after tire replacement or repair; false alarms are common after temperature drops in winter; vehicles with modified rims may require special equipment to reset tire position recognition. Last time my car alarmed again after reset, it turned out the wheel speed sensor was dirty—cleaning it completely resolved the issue.
