What does the afsoff warning light indicate?
2 Answers
afsoff is the malfunction indicator for the automatic headlight beam leveling system. A vehicle's lighting system includes exterior lights such as headlights, fog lights, license plate lights, reverse lights, turn signals, as well as various interior lights like instrument panel lights, reading lights, and dome lights. When these lights malfunction, it can affect normal vehicle operation and driving safety, causing inconvenience and even posing hazards during nighttime driving. These lights are controlled by different positions of a combination switch. Most failures are caused by burnt-out bulbs or wiring issues, and the reverse power supply inspection method can quickly locate the fault. First, check the bulb - if it's burnt out, simply replace it. If the bulb is intact, inspect its grounding circuit. If the grounding connection is secure, examine the power supply wiring to the bulb. Most faults occur in the power wires or connectors behind the bulb, eliminating the need to check the light switch or relay.
When the AFS OFF light appears on the dashboard, it indicates that the Adaptive Front-lighting System has been deactivated. This means the headlights cannot automatically adjust their angle to illuminate curves during turns. The issue is likely caused by sensor malfunctions, such as a faulty steering angle sensor detection or unstable speed sensor signals. It could also be due to loose wiring connections or a malfunctioning control module. I've encountered this before—the system may shut down as a self-protection measure when detecting voltage fluctuations or excessive road bumps, compromising nighttime curve visibility. It's crucial to scan for trouble codes promptly using a diagnostic tool to pinpoint the exact cause and prevent further damage. Sometimes restarting the vehicle may temporarily resolve it, but if the light frequently reappears, it's best to have a professional workshop inspect the hardware components to ensure worry-free daily driving.
