What does the Buick LaCrosse dashboard's AFL maintenance light indicate?

Possible causes are as follows: 1. Inside the headlight: The headlight's internal steering mechanism is stuck or the drive motor is damaged. 2. Sensor: The AFL steering sensor is damaged. 3. Wiring: Loose or disconnected wiring interfaces. 4. Battery: The front headlight high-speed adjustment control module's front axle sensor signal circuit is short-circuited to the battery. Additional relevant information: 1. Reset: The AFL light cannot be manually reset by the owner; it requires inspection at a 4S shop. The light will naturally disappear after repairs. Based on owner feedback, this phenomenon often occurs in older vehicles that have been driven for several years. Sometimes, it's not an issue with other circuits or sensors; the AFL light may also appear as a precursor to the headlights failing. 2. Problem-solving approach: Based on the car's steering wheel angle, yaw rate, and driving speed, the headlights can be dynamically adjusted continuously to adapt to the current steering angle, ensuring the light direction aligns with the vehicle's current driving direction. This provides optimal illumination of the road ahead and maximizes visibility for the driver, significantly enhancing driving safety in the dark.
