How to Turn Off the Headlight Control Range Malfunction?

When the headlight level adjustment warning appears, it indicates that the headlight beam direction has deviated from the standard direction. You need to take your vehicle to a repair shop for maintenance and then use a fault diagnostic tool to clear the fault code. Depending on the vehicle model, access the corresponding diagnostic system; read the fault code; check the data stream; after diagnosis and repair, clear the fault code by reading and clearing the fault code.
I also had a headache with this issue last time. That night when driving on a suburban road, the system suddenly reported a fault, the lights were flickering wildly, and it almost caused an accident. The next day, I removed the trunk floor panel and found the level sensor linkage of the rear suspension was stuck. After lubricating it with WD-40 and moving it a few times, it worked normally again. Actually, 90% of this fault is due to sensor issues. There's one sensor at the front and rear of the vehicle, responsible for monitoring height changes. If they're covered in mud or the linkage is deformed, the system will report an error. Vehicles with modified suspensions are particularly prone to this problem, so it's best to check and clean the sensors every quarter. Now, my habit is to rinse the sensor locations under the chassis when washing the car, and I haven't encountered similar faults in the past three years.
