Power door locks in the Suzuki Cultus may lock o r unlock on their own due to several issues:
Faulty Door Lock Actuator: A malfunctioning actuator can cause the doors to lock o r unlock randomly. This is because the actuator may not properly recognize when it’s supposed to engage, causing the locks to operate erratically.
Electrical Glitch o r Short Circuit: Electrical problems, such as a short circuit in the wiring o r issues with the central locking control unit, can cause the locks to operate without input from the key fob o r door switches. This could happen due to poor wiring o r loose connections.
Malfunctioning Key Fob: A stuck button o r malfunctioning internal circuitry in the key fob can send signals to the car’s locking system, causing the doors to lock o r unlock on their own.
Central Locking System Failure: The central locking system, which controls all the door locks from a central module, can malfunction due to software issues o r a hardware failure, leading to random lock/unlock behavior.
How to Fix:
Inspect and Replace the Actuator: If the actuator is malfunctioning, it will need to be replaced.
Check Electrical Connections: Inspect the wiring and connections in the central locking system for any faults. Tighten loose connections and repair any damaged wiring.
Test the Key Fob: Ensure the key fob buttons are functioning properly. Replace the key fob battery and check for any stuck buttons.
Reset the Central Locking System: If the issue is with the central locking system, it may require a reset o r reprogramming by a professional technician.
