How to Check the Tire Pressure Monitoring System on Hyundai Elantra?
1 Answers
Hyundai Elantra's tire pressure monitoring system is generally displayed on the dashboard screen, but the tire pressure cannot be shown when the vehicle is stationary. The tire pressure monitoring system automatically and continuously monitors the tire pressure while driving, alerting the driver to tire leaks or low pressure to ensure driving safety. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: The direct tire pressure monitoring system uses 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 the data for each tire's pressure is displayed. 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 become smaller, making it rotate faster than the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. The indirect tire pressure alert system essentially relies on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): This system combines the advantages of the two aforementioned systems. It is equipped with direct sensors in two diagonally opposite tires and includes a four-wheel indirect system. Compared to a fully direct system, this hybrid system reduces costs and overcomes the indirect system's inability to detect low pressure in multiple tires simultaneously. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.
