What is the reason for the failure of the car central locking system?

[Janelle]

The failure of the car central locking system is mainly caused by malfunctions in the door lock actuator and the door lock controller. If this situation occurs, the car owner should promptly take the vehicle to a repair shop for inspection. The fault information can be quickly detected using a diagnostic tool. Below are some additional details: Central Control: When the driver locks the door next to them, all other doors are simultaneously locked. The driver can use the door lock switch to open all doors at once or open a specific door individually. Speed Control: When the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening the doors by operating the door handles. Individual Control: In addition to the door next to the driver, other doors are equipped with separate spring lock switches, allowing independent control over the locking and unlocking of each door.
