How to Solve the Issue of the Central Control Not Powering Off When Locking the Car?

[Kathleen]

The solution to the central control not powering off when locking the car is: 1. Use the method of disconnecting the entire vehicle's power. Open the trunk and locate the grounding wire under the right side of the trunk carpet; 2. Disconnect the grounding wire to cut off the battery power; 3. Wait for a few minutes before reconnecting it to restore power, and the central control screen will return to normal. The display on the central control panel mainly shows car audio, navigation, vehicle information, reverse camera feed, etc., and includes both single-touch and multi-touch LCD screens. In most car models, the central control color screen is located near the central control panel. During use or storage of the car, care should be taken with the surface polarizer of the LCD screen to avoid scratches from hard objects, and placing hard items on the LCD screen is strictly prohibited.

I've also encountered the issue where the center console remains lit after locking the car. Later, I found out it was a minor glitch in the electrical system, possibly because the door switch didn't fully sense the lock or the relay got stuck. The simplest solution is to check if all doors and the trunk are properly closed—that day, my trunk wasn't securely locked, causing the center console to stay powered. Closing it tightly fixed the issue. If that doesn’t work, check the fuse box to see if the fuse corresponding to the center console circuit has blown, and try replacing it. Occasionally, low battery in the remote key can also affect signal recognition, so replacing the battery might solve it. Also, disconnecting the car battery for a few minutes to reboot the system works well—it’s like a soft reset. I recommend starting with these basic checks to avoid prolonged battery drain. If the problem persists, it’s best to visit a repair shop, as a center console that doesn’t power off not only drains the battery but could also pose safety risks. Safety first!

After locking the car, the central control system stays on continuously. As an ordinary car owner, I'm quite concerned because this might indicate issues with the door sensors or the central control module. I usually try locking the car several times first, ensuring all doors click securely—sometimes they appear closed but aren't fully in place. Next, I test if the remote key functions properly, as low battery power can affect command recognition. If the problem persists, I open the hood to check the fuse box, looking for any blown fuses related to the central control system. If found, replacing it with a matching one is a simple and cost-effective solution. Additionally, disconnecting the negative battery terminal for 5 minutes and then reconnecting it can reset the system. I've tried this with good results, but remember that settings will be lost after the reset. During the process, be cautious to avoid electrical contact. If you can't resolve it yourself, don't hesitate to consult a professional technician to prevent minor issues from escalating. Prolonged issues could drain the battery, making it harder to start the car. In short, stay calm and methodical—you'll find the cause step by step.

I've encountered this issue of the central locking system not powering off multiple times. The root cause is likely a stuck relay or software malfunction. First, manually check the door closure sensors to ensure each door is fully shut without gaps, and don't forget the trunk. Then remove the car key or confirm the remote signal is transmitting properly - sometimes a simple reboot works. If ineffective, locate the central locking circuit fuse in the fuse box and test for continuity with a multimeter, replacing if blown. The relay in the box might also be jammed; gently tap it to see if it releases the connection. As a last resort, disconnect the battery negative terminal for a few minutes to reset, then test the locking function after reconnecting. The entire process isn't complicated but avoid touching live components. Address it promptly to prevent excessive battery drain affecting next-day use.

I've dealt with similar issues before and found that the center console not turning off after locking the car is often caused by electronic system bugs in Hyundai vehicles, such as sensor signal confusion. My usual approach is to first ensure all doors and windows are completely closed, then try manually locking the car with the key to eliminate remote interference. Next, I check the fuse locations, typically found under the steering wheel or in the engine compartment - if blown, simply replace them with the correct amperage. Disconnecting the battery and waiting is a classic method to reset the circuit; when I did this overnight, the system rebooted normally the next day. Additionally, if aftermarket audio modifications are involved, incorrect wiring might cause backfeed, requiring inspection of the original wiring. Letting such faults persist can damage the battery and waste energy, so I recommend DIY checks for quick resolution, but if that doesn't work, visit a 4S shop for professional diagnosis to ensure the root cause is properly addressed.
