How to Check the Tire Pressure Monitoring System?

Tire pressure monitoring system can be viewed on the central LCD screen of the instrument panel or the multimedia screen. The tire pressure monitoring system automatically monitors the tire pressure in real-time during driving and alerts the driver in case of tire leakage or low pressure to ensure driving safety. 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. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the pressure of a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS): It combines the advantages of both 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 direct systems, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data of the actual pressure in all four tires as direct systems do.
