What is the reason for the Song Pro simultaneously displaying low tire pressure in all four tires?
1 Answers
If the Song Pro displays low tire pressure in all four tires simultaneously, it is most likely due to a malfunction in the tire pressure monitoring system, causing confusion in the tire pressure information. Resetting the tire pressure monitoring system should resolve the issue. Another possible reason could be weather-related changes, as tire pressure fluctuates with temperature variations. If the issue is weather-related, there is no need to worry—once the temperature rises, the tire pressure will increase accordingly. Lower temperatures can cause tire pressure to drop, while higher temperatures can cause it to rise. Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver to leaks or low pressure to ensure driving safety. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure readings for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to shrink, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire pressure monitoring relies on calculating the rolling radius to detect pressure changes. Tire Pressure Monitoring System (TPMS) Overview: This system combines the advantages of both direct and indirect monitoring. It equips two diagonally opposite tires with direct sensors and includes a four-wheel indirect system. Compared to a fully direct system, this hybrid approach reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires like a fully direct system.
