What are the reasons for the GL8 center control screen not turning off?
2 Answers
The main reasons are as follows: 1. Delayed shutdown setting. The vehicle's computer display is set to turn off with a delay after the engine is turned off. This design allows the owner to check the day's vehicle usage data after using the car, hence the delayed shutdown setting. 2. Circuit malfunction. You can observe whether the screen continues to stay on after turning off the engine and locking the car. If it remains on for an extended period, it needs to be checked promptly; otherwise, it may drain the battery, making the vehicle unable to start. If the navigation screen stays on after turning off the engine, a car diagnostic tool is required at this point. Additional notes: 1. Damage from external power sources. Leaving external power sources connected after turning off the car, such as charging power banks or phones, can be very harmful to the vehicle. 2. Frequent engine starts and stops. If the weather is extremely cold or hot, and the owner turns off the engine only to restart it to use the air conditioning, such unnecessary frequent starts and stops can cause significant harm to the car. This also damages the car battery by over-discharging, reducing its lifespan.
I've been driving a GL8 for ten years and have encountered the issue of the center console screen not turning off after the engine is shut down a few times. It's usually related to power supply or software. On the power side, it could be a blown fuse or poor contact in the battery wiring, causing continuous power to the screen. Software-wise, the infotainment system might be stuck in standby mode and not detecting the shutdown signal. Additionally, if the door sensor doesn't detect that the door is closed, the system may think someone is still using the car. Not addressing this promptly can affect the battery's lifespan, making it difficult to start the car the next day. I've even experienced a dead battery stranding me. Daily, it's advisable to turn off the large screen power setting before shutting down the engine. If the problem occurs frequently, it's best to visit a 4S shop to check the ECU and reset the infotainment system, which usually resolves the issue. Similar problems are more likely to occur after long-distance driving because the system has been running under heavy load for an extended period.
