How to Solve the Random Jumping Issue of the Excelle's Central Locking System?

[LeAllie]

If the central locking system of the Excelle exhibits random jumping behavior, it is necessary to visit a 4S shop to replace the door lock control assembly and the central control module. Below is relevant information: 1. Definition of the Central Locking System: The central locking system, fully known as the central control door lock, is an automotive accessory that allows remote opening and locking of doors without inserting the key into the lock. It consists of a door lock switch, an actuator, and a controller. 2. Basic Principle of Remote Control: A weak radio wave is emitted from the vicinity of the car owner, received by the car's antenna, and the signal code is identified by the electronic control unit (ECU). The system's actuator (motor or electromagnetic coil) then performs the locking or unlocking action. This system mainly comprises a transmitter and a receiver. 3. Functions: (1) Central Control: When the driver locks the door next to them, all other doors are simultaneously locked. The driver can open all doors via the door lock switch or open a single door individually. (2) 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. (3) Individual Control: Besides the door next to the driver, other doors are equipped with separate spring lock switches, allowing independent control over the opening and locking of each door.
