[StViolet]

The reason for the erratic jumping of the Excelle's door lock latch is the damage to the small switch inside the central control motor of the left front door. Below are the relevant details about the central locking system: Central Locking System: The full name of the central locking system is Central Control Door Lock, which is an automotive accessory. Using this lock allows for remote opening and locking of doors without inserting the key into the lock cylinder. It consists of the door lock switch, actuator, and controller. Main Functions: It is divided into central control, speed control, and individual control. Central control means that 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 means that when the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening the door by operating the door handle. Individual control refers to the presence of separate spring lock switches on doors other than the driver's side, allowing for independent control of the opening and locking of a single door.
