The reason why the car display screen is still on after the engine is turned off is: there is a problem with the power supply module, and the relay needs to be checked and repaired in time. At this time, you can use a car diagnostic tool to detect, enter the SMK system to read the data stream. If the data stream ACC and ACC input circuit and battery circuit are all in the ON state when the engine is off, it means that it is currently in a short circuit state. The display screen includes the central control door lock system, central console, and audio control panel. Its functions are: 1. The central lock actuator can be used to execute the driver's instructions to lock or unlock the door; 2. Control the adjustment of memory seats, music system adjustment, entertainment system adjustment, roof camera function, and automatic parking function.

What to Do When the Car Handbrake Fails?

The solutions for a failing car handbrake are: 1. Replace the brake pads and brake discs; 2. Add brake fluid; 3. Replace the brake vacuum booster and vacuum tube. The function of the car handbrake is to lock the drive shaft or rear wheels when parking, providing resistance to prevent the car from rolling. The handbrake, also known as the auxiliary brake, operates differently from the main brake system. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation, which is irreversible. Over time, this reduces the effectiveness of the handbrake and increases its travel distance.

What is the solution to the rear seat resonance in the Song DMI?

Song DMI rear seat resonance solution is to adjust the rear seats. Disadvantages of the Song DMI: The interior is generally acceptable, but the workmanship in some areas is not good, with large gaps at the joints; this car uses a dual-clutch transmission, so at low speeds, the gear shifting is not very responsive, and the jerkiness is quite noticeable—it would be better if it used a 6AT transmission; the vehicle's noise insulation is poor, mainly manifesting as wind noise and tire noise. As soon as the speed increases slightly, noise becomes noticeable inside the car. Advantages of the Song DMI: The space is relatively large, and even when fully loaded, there is no crowding; the power is very strong, and the handling is excellent.

How to Solve Excessive Tire Noise?

Tire noise can be addressed through the following methods: 1. Remove debris such as stones stuck in the tire treads, as this significantly helps reduce tire noise. Particularly, larger stones lodged in the treads can cause substantial noise when rubbing against the road surface. 2. Cleaning the tires also contributes to noise reduction. If the tire noise is excessive, washing the tires can help diminish the noise. 3. If tire noise is too loud, performing a dynamic balance on the tires may also be beneficial. 4. For vehicles with high mileage, getting a four-wheel alignment can help. 5. Maintain proper tire pressure. Both overinflation and underinflation can lead to increased tire noise.
