The dreaded AFLS (Adaptive Front Lighting System) warning light on a Hyundai dashboard can be a source of frustration. This article addresses a common issue with the AFLS system in a 2013 Hyundai i40, focusing on a misaligned projector within the headlight housing. We’ll explore possible causes, diagnostic steps, and potential solutions.
Understanding the Hyundai AFLS System
The AFLS system enhances visibility by automatically adjusting the headlight beams based on steering angle and vehicle speed. A malfunctioning AFLS can significantly impair night driving safety. Common issues include bulb failures, faulty sensors, and problems with the AFLS control module. In this case, the problem stems from a dislodged projector within the headlight assembly.
Diagnosing a Misaligned Headlight Projector
The author noticed the misalignment after replacing a headlight bulb. The projector, responsible for focusing the light beam, was no longer centered. While the system attempted to self-correct, the driver’s side headlight remained pointed inwards, towards the center of the vehicle, as shown in the images below.
This misalignment suggests a potential mechanical issue within the headlight assembly. The projector might have become detached from its motor or the motor itself could be malfunctioning. While the AFLS module might be implicated, it’s crucial to rule out physical damage to the headlight assembly first.
Potential Solutions and Next Steps
Before replacing the AFLS module, a thorough inspection of the headlight assembly is recommended. This involves carefully examining the projector’s connection to its motor and checking for any loose or broken components. Attempting to manually adjust the projector (if possible) might provide a temporary fix. However, professional assistance is likely required for a permanent solution.
Using a diagnostic scanner to retrieve the error code associated with the AFLS warning light is crucial. This code will pinpoint the specific fault within the system, enabling a more accurate diagnosis. The code will help determine if the problem lies with the projector motor, a sensor, wiring, or indeed the AFLS module itself. Researching the specific error code online can provide further insights into the issue and potential solutions.
Once the root cause is identified, appropriate repairs can be undertaken. This might involve reattaching the projector, replacing the projector motor, or addressing any issues with the AFLS control module. Given the complexity of the AFLS system, consulting a qualified Hyundai technician is advisable for accurate diagnosis and repair.
