What is the reason for the absence of turn signal and seat belt warning sounds?
1 Answers
It may be due to a problem with the control system, and it is necessary to visit an auto repair shop for inspection and resolution. Below are relevant introductions: 1. The function of turn signals: Turn signals are important indicator lights that are turned on when motor vehicles are turning to alert vehicles and pedestrians in front, behind, and on both sides. The turn signal bulb uses a xenon tube, with a microcontroller-controlled circuit that alternates left and right in continuous flashing operation. The turn signal employs a flasher to achieve the blinking effect. 2. The function of seat belts: Car seat belts are devices used in vehicles to reduce passenger and driver injuries when the car body is subjected to a violent impact. In the event of a collision, the passenger's body continues to move forward due to inertia, colliding with the car interior, and in severe cases, may shatter the windshield and be thrown out of the window. To prevent such injuries during a crash, public security departments require all front-seat passengers to use seat belts in case of a traffic accident.
