Why doesn't the seat belt reminder sound anymore?

[CollinLee]

The seat belt reminder may not sound for the following reasons: the sensor has a problem and does not detect, so it won't sound; the seat belt socket is damaged, you can check it; the weight is too light for the sensor to detect; the safety alarm plug may be loose or broken; check the safety alarm circuit to see if the buzzer is damaged. Relevant information about car seat belts is as follows: 1. Introduction: The car seat belt is a safety device designed to restrain occupants during a collision and prevent secondary collisions between occupants and the steering wheel or dashboard, or to prevent occupants from being thrown out of the vehicle, which could lead to injuries or fatalities. 2. Working principle: The retractor contains a ratchet mechanism. Under normal circumstances, occupants can pull the webbing freely and evenly on the seat, but when the webbing is continuously pulled out from the retractor and suddenly stops or when the vehicle encounters an emergency, the ratchet mechanism will lock automatically to prevent the webbing from being pulled out.
