How to Check the Tire Pressure Monitoring in RAV4?
1 Answers
RAV4's tire pressure monitoring is not an active monitoring function. It only automatically displays information on the dashboard when there is an abnormality in the tires. The display does not show specific values but only indicates which tire has an issue. Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver to tire leaks or low pressure to ensure driving safety. Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the data for each tire's pressure. The system automatically alerts when tire pressure is too low or 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 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 tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above, equipping direct sensors in two diagonally opposite tires and incorporating a 4-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.
