How to Fix the AFS OFF Light?
3 Answers
AFS OFF light indicates that the headlight's adaptive front-lighting system (AFS) is turned off. Re-enable the AFS function. Check the AFS module, use a diagnostic scanner to match settings and clear fault codes to resolve the AFS warning light. AFS stands for Adaptive Front-lighting System. If the indicator light stays on, it means this function is currently disabled. Ensure the vehicle's power is off, then open the hood and locate the negative terminal of the battery.
The AFS OFF light being on is really worrying. I remember the last time this happened, I first tried to see if there was an AFS switch button inside the car or a dashboard settings menu to check if the system was accidentally turned off manually. If the system status is off, just turn it on; if it's on but the light is still on, then the system might be faulty. This adaptive front lighting system works with sensors, such as the steering wheel angle sensor, which can wear out or malfunction after long drives or on bumpy roads. In this case, try restarting the engine. If that doesn’t work, don’t force it, especially on winding mountain roads at night where the lights not adjusting automatically can be very dangerous. I’ve learned that regularly checking these electronic devices can avoid costly repairs—safety comes first. It’s still best to go to a 4S shop for professional diagnostics, as modern car systems are complex, and tampering with them yourself can easily damage more parts.
Oh no, the AFS OFF light on the car suddenly came on. I've encountered this several times, so don't panic too much. First, check the settings near the steering wheel or the central control screen to confirm if the AFS system was accidentally turned off. If the system is on but the light remains, common causes include sensor failure or loose electrical connectors, possibly due to moisture after rain causing temporary issues. After restarting the car, drive for a while to see if the light disappears. Also, pay attention to other indicator lights like the ESP light coming on as well, which might indicate an issue with related systems. As for repairs, the cost isn't high—a regular shop can replace a sensor for a few hundred bucks. However, delaying repairs can affect driving assistance functions, so try not to put it off. I also recommend installing waterproof covers to protect critical components, as regular maintenance can extend their lifespan.
