1 Answers
If the central locking system of the Excelle exhibits random jumping, it is necessary to visit a 4S dealership to replace the door lock control assembly and the central control module. The repair cost is approximately 500 yuan. Below is more information about the central locking system: 1. What is a central locking system: The full name of the central locking system is Central Control Door Lock, which is an automotive component. Using this lock allows for remote opening and closing of doors without inserting the key into the lock. It consists of a door lock switch, an actuator, and a controller. 2. Functions of the central locking system: Central control - when the driver locks the door beside them, all other doors are simultaneously locked. The driver can open all doors via the door lock switch or open a single 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 beside the driver, other doors are equipped with separate spring lock switches, allowing independent control of each door's opening and locking. 3. Basic principle of remote control: A weak radio wave is emitted from the owner's vicinity, received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the lock/unlock action. The system mainly consists of two parts: a transmitter and a receiver.
