What are the reasons for tire pressure monitoring system failure?

[McTheo]

The reasons for tire pressure monitoring system failure are: 1. The battery of the tire pressure sensor is depleted; 2. Sensor signal failure; 3. Sensor circuit failure; 4. Body control module failure. The functions of tire pressure monitoring are: 1. To alert promptly in case of rapid or slow air leakage when the tire is punctured; 2. To alert when tire looseness causes unbalanced friction, leading to tire temperature reaching 70 degrees Celsius to prevent blowouts; 3. To alert when the tire pressure is below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing tire temperature rise and blowouts. The method to reset the tire pressure monitoring is: 1. Ensure the vehicle's tire pressure is within the normal range; 2. Park the vehicle on a flat surface and turn off the engine; 3. Power on the vehicle and hold down the tire pressure monitoring button; 4. After 5 seconds, upon hearing an alarm sound, release the button to complete the reset successfully.
