What is the fault of Haval ALS?
4 Answers
When the Great Wall Haval H6 car displays an ALS system fault, it means there is an issue with the Automatic Leveling System. Relevant information is as follows: Solution: Visit a Great Wall Haval 4S store for a comprehensive inspection and repair of the car's leveling system to resolve the issue with the automatic leveling system. ASL: ASL is also a device configured for automatic transmissions, but its installation position differs. ASL is integrated into the entire gear shift system. ASL is a safety measure to prevent sudden vehicle acceleration. This system requires the driver to press the brake pedal when starting the car before shifting from P (Park) or N (Neutral) to R (Reverse) or D (Drive), preventing the vehicle from moving without braking.
As a Haval owner, I recently encountered an issue where the ALS (Adaptive Lighting System) wasn’t working. During a night turn, the headlights remained fixed, making it almost impossible to see the road clearly. Possible causes could be a sensor blocked by mud or dust, or internal module damage. Initially, I thought it was a minor issue, but delaying for two days made it worse. At the repair shop, the technician mentioned the most common causes are software bugs or water seeping into the wiring. They performed a software update and cleaning, which quickly resolved the problem. I recommend checking warning lights after starting the car and not ignoring minor abnormalities to prevent accidents. Regular cleaning of external cameras and keeping software updated can help avoid such issues in advance.
Having driven for many years, common ALS faults such as the lights no longer automatically adjusting to the road direction are mostly caused by water ingress in the sensors or control unit failure. The sensors are located near the front bumper of the car and are prone to dirt or moisture. First, try gently wiping them with a cloth. Sometimes, restarting the vehicle or updating the car's software can also resolve the issue. If the problem persists, it might be due to a short circuit or module aging, so be sure to get it repaired promptly to avoid risks during night driving. Don't rush to replace parts—a simple diagnosis can save both time and money.
The Haval ALS system is super practical but occasionally malfunctions. In my case, the lights suddenly stopped turning automatically. Possible causes could be software lag or dirty sensors. Simple solution: try cleaning the camera lens yourself or turning off and restarting the engine to see if it helps. If the problem persists, go to a professional repair shop immediately to avoid compromising driving safety. Don't delay too long, as small issues can turn into big troubles.
