How to Resolve High Beam Assist Malfunction?
2 Answers
You need to take the vehicle to a repair facility where professional diagnostic equipment can be used to read the fault codes stored in the system. Further determine the cause of the malfunction, and through data measurement and comparison, identify the root cause of the issue and implement the necessary repairs.
I also experienced a high beam assist malfunction in my own car, which was particularly inconvenient when driving at night as it often failed to switch automatically. The first step I took was to check in the car settings to confirm whether the system was turned on, as sometimes it can be accidentally disabled. If it was on but still problematic, I would inspect the camera or sensors on the windshield for any obstructions like bird droppings or dust, gently wiping them clean with a damp cloth to see if that helped. If that didn’t work, I’d try restarting the car—turning it off for a few minutes and then restarting it to reset the system. Once, it turned out to be a software bug, and updating the car’s system as per the manual resolved the issue. If none of these steps worked, it might indicate hardware damage or wiring issues, requiring a visit to a 4S shop or professional repair center to scan for fault codes with a diagnostic tool to pinpoint the cause and replace parts, such as the sensor module. To minimize such issues, it’s good practice to keep the car clean and have technicians inspect this system during regular maintenance.
