Changan CS75 tire pressure monitoring fault clearing method: Press the square icon button on the left side of the steering wheel to switch to the tire pressure detection screen, then hold down the triangle icon button to reset. Tire Pressure Monitoring: Tire pressure monitoring is the real-time automatic monitoring of tire pressure during vehicle operation, with alerts for tire leaks and 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 tire pressure. Wireless transmitters send pressure information from inside the tire to a central receiver module, which then displays the tire pressure data. 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, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Introduction: 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 direct systems, this hybrid system reduces costs and overcomes the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires like a direct system.
