What causes the central locking system failure in a 2012 Hyundai Tucson?

[EllianaDella]

Common failures in automotive central locking systems typically include: motor aging requiring replacement, blown fuses in the switch circuit needing replacement, malfunctioning central locking control unit requiring replacement, and loosened linkage rods of the main motor needing tightening. For instance, issues like blown fuses can only be resolved by direct replacement, unless it's a mechanical component that can be repaired. Introduction to central locking system functions: 1. Central control: When the driver locks their door, all other doors lock simultaneously. The driver can unlock all doors via the door lock switch or open a specific door individually. 2. Speed control: When the vehicle reaches a certain speed, all doors automatically lock to prevent accidental door handle operation by passengers. 3. Individual control: In addition to the driver's door, other doors feature separate spring lock switches that allow independent control of each door's locking and unlocking.
