Central locking system failure is usually caused by issues with the fuse of the locking system or faults in the door lock relay components. It cannot be self-repaired and requires inspection and maintenance at a 4S shop. The automotive central locking system is designed for convenient and safe vehicle use, providing centralized control over the locking and unlocking of all four doors. Its working principle involves converting electrical energy into mechanical energy, using a motor to drive gears for door opening and closing operations. The central locking system mainly consists of door lock switches, door lock actuators, and door lock controllers. Basic functions of central locking: 1. Central control - When the driver locks their door, all other doors lock simultaneously. The driver can unlock all doors simultaneously via the door lock switch or open individual doors separately; 2. Automatic locking - All doors automatically lock when the vehicle reaches a certain speed.
