What are the common faults of car central locking systems?

[DiMaya]

Common faults in car central locking systems include malfunctioning locks that prevent doors from securing. Modern vehicles feature various types of central locks, but their basic components mainly consist of door lock switches, door lock actuators, and door lock controllers. When central locks fail to secure doors, the issue typically lies with the door lock actuators or controllers. If this occurs, owners should promptly visit repair shops for diagnostics, as specialized equipment can quickly identify fault codes. Below are self-inspection methods: 1. First verify proper installation of components and wiring connections, then check whether power cables (live wires) and ground wires maintain secure connections to the battery. If no abnormalities are found, this indicates potential faults in the electronic control switch box, damaged lock switches, or circuit malfunctions requiring detailed inspection. 2. If only one or two door locks remain inoperative, the probable causes are damaged door lock motors, broken wiring, or mechanical transmission failures in those specific doors.
