Why is the digital display of Haval tire pressure monitoring not showing?

This issue is mostly caused by a malfunction in the built-in tire pressure detection method. This built-in tire pressure detection system mainly consists of an internal module and a display screen. The probability of the display screen malfunctioning is relatively low. The most likely cause is a failure in the internal detection module. There are three commonly used tire pressure monitoring methods: Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When the tire pressure is too low or there is a leak, the system will automatically issue an alarm. Indirect tire pressure monitoring: When the pressure of a tire decreases, the weight of the vehicle will cause the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the purpose of monitoring tire pressure is achieved. Indirect tire pressure alarm systems actually rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a 4-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the defect of indirect systems being unable to detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data of the actual pressure in all four tires like a direct system.
As a long-time Haval owner, I've encountered situations where the tire pressure monitoring numbers didn't display, and upon investigation, there are quite a few reasons. The most common is the battery in the tire pressure sensors running out—these little devices have built-in batteries that last about 5 years, and once depleted, they can't send signals. Or the sensor might be damaged, like when the tire hits a rock and the signal is interrupted; the system might also have a delay in activating if the car hasn't reached speeds above 20 km/h; or the display function might have been accidentally turned off in the settings menu. I recommend trying to fix it yourself first by driving at highway speeds to activate the signal. If that doesn't work, try resetting the TPMS system in the vehicle settings. Don't ignore this issue—proper tire pressure can save fuel and prevent blowouts. Make sure to visit a professional repair shop promptly to check for safety risks.
Hey buddy, as a car enthusiast who often tinkers with electronic systems, I've found that when the tire pressure numbers don't display on my Haval, it's usually one of these issues. The most common is the sensor battery running out, or signal interference like nearby high-power equipment blocking communication; software bugs requiring an update or reset; or new tires not being paired with the system in time. I've tried finding the reset option in the settings menu, and it works pretty well. Also, regular maintenance lets the technician check the sensor health—don't wait for an accident to regret it. Tire pressure monitoring protects tire lifespan and driving safety.
