What about the abnormal tire pressure monitoring alarm of the new Regal?

Answer: Please check the left rear wheel pressure monitoring sensor at the 4s shop. If the sensor is normal, it is necessary to check whether there is local wireless interference in the car (such as poor contact of some instrument lines due to the imprecise installation process of adding gps). The working principle of the tire pressure monitoring system of the new Regal is that there is a pressure monitoring sensor in each wheel/tire assembly, which sends the sensor identification number, tire pressure and battery low level through wireless fixed frequency communication. When the vehicle is stationary, the accelerometer inside the sensor does not start, which makes the sensor enter a static state. In this state, the sensor samples the tire pressure every 30 seconds. If the tire pressure remains unchanged, it will not be transmitted. When the vehicle speed increases above 20km/h (15mph), the centrifugal force starts the accelerometer inside the sensor, and the sensor enters the rolling mode. In this mode, the sensor samples tire pressure and temperature every 10 second, and emits it every 60 seconds in rolling mode. If the tire pressure changes by 8.3 kPa (1.2 psi), the sensor will send it immediately.
