Is It Normal for the Envision's Tire Pressure Monitoring System to Require Re-matching?

[DelMaci]

Method for re-matching the Envision's tire pressure monitoring: Start the vehicle, locate and press the SET button on the left side of the multifunction steering wheel, then confirm the operation by pressing the checkmark button on the right side of the multifunction steering wheel. Once successfully matched, the tire pressure display on the central dashboard will return to normal. There are three common methods of tire pressure monitoring: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the 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. 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 wheel to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between the tires, the system monitors the tire pressure. Essentially, the indirect tire pressure alert system relies on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): This system combines the advantages of both the direct and indirect systems. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to using only a direct system, this hybrid approach reduces costs and overcomes the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a full direct system.
