The reason why the car's central control screen stays on and cannot be turned off is due to a malfunction in the central control system. As the most important and complex onboard electrical device in the car, the central control system is prone to lagging and malfunctions over time, making it the most common area for issues. Solutions for a car central control screen that stays on and cannot be turned off: Use a car diagnostic tool to access the SMK system, read and observe the data stream. Check whether the data stream shows the "ACC" input circuit and the battery circuit in the ON state when the engine is off. If not, the circuit is fine; if yes, the circuit is in a short-circuit state. Debug the power supply module and inspect or repair the relay. If the driver is not very familiar with circuits, it is advisable to take the vehicle to a local 4S shop for professional handling to avoid accidental damage to the internal system components. Functions of the car central control: The car central control is responsible for managing comfort and entertainment devices such as the air conditioning and audio system. It includes the central door lock system, allowing the driver to control all door switches and window lift systems. The central door lock system primarily features three functions: central control, speed control, and individual control. The driver can control all door locks, and when the vehicle reaches a certain speed, the doors automatically lock. Each door also has an independent switch for individual control. The car central control also includes the central console, which houses various vehicle controllers like the audio control panel.
