How to resolve the Toyota AFS off light being on?
3 Answers
AFS off light staying on indicates that the vehicle's Adaptive Front-lighting System (AFS) is currently turned off. Here are the relevant details: 1. If you need to turn the system on, you can press the button again to activate the system, and the indicator light will turn off. If the "AFS OFF" indicator on the instrument panel flashes, it means there is a fault in the system. For repairs, you need to take the vehicle to a service center, where professional diagnostic equipment can be used to read the fault codes stored in the system. This helps further identify the cause of the fault, and through data measurement and comparison, the root cause can be found and resolved. 2. The Adaptive Front-lighting System (AFS) adjusts the direction of the front light beam according to the current driving conditions. The system moves the front light beam left or right based on the vehicle speed and steering wheel angle. This system works in conjunction with the automatic headlight leveling system to improve visibility at intersections and during turns. The system starts operating when the vehicle speed exceeds 10 km/h.
As someone who has been repairing Toyotas for a long time, I've seen many cases where the AFS Off light comes on. This light indicates that the Adaptive Front-lighting System is turned off or malfunctioning. First, check if you accidentally pressed the AFS button near the steering wheel, then press it again to see if the light turns off. If that doesn't work, it might be because the windshield camera is dirty, blocking the sensor. I'd recommend cleaning it yourself to see if that helps. Another common cause is a burnt-out headlight or a blown fuse on one side. Open the hood and inspect the corresponding section of the fuse box. If the light remains on after restarting the car, it's likely that the control module is faulty. It's best not to delay and take it to a dealership to read the fault codes with specialized tools for repair. This system automatically adjusts the headlights during nighttime turns, significantly improving safety. Don't risk an accident by neglecting a small issue. Regularly cleaning the sensor area during car washes can help prevent problems.
I recently experienced the Toyota AFS Off light coming on and want to share how to handle it. I was quite startled at first, but after checking the manual, I found that the first step is to check if the AFS switch was accidentally turned off - pressing it again might solve the issue. If that doesn't work, clean the sensors under the windshield as dust buildup can trigger false alerts. I also verified that all lights were functioning properly in case a bulb had burned out. If the light stays on persistently, don't risk driving at night - it's too dangerous. I recommend going straight to a service station. After resolving that issue, I've made it a habit to regularly check the system. Toyota's AFS is very useful, but problems need quick attention. The whole process is straightforward, and in most cases, you can handle it yourself.
