Common Questions

What does B0AD3 mean and how does it affect my car?

B0AD3 indicates there's an issue with your vehicle's Adaptive Front Lighting System, which could lead to improper headlight alignment, reducing your visibility at night. This malfunction can make it unsafe to drive under low-light conditions, as other drivers may not see you well, nor will you see the road ahead clearly.

What are the most common causes of B0AD3 and how much does it cost to fix?

The most frequent cause of B0AD3 is a faulty AFS control module, which can cost between $300 and $600 to replace. Other causes can include misalignment of headlights, which may only require a simple adjustment costing about $50 to $150. Regular maintenance can help to prevent these issues.

Can I drive my car with B0AD3 or should I stop immediately?

It's advisable to address the B0AD3 code as soon as possible. Driving with malfunctioning headlights can significantly impair your vision and the visibility of your vehicle to others, posing a safety risk. If you notice symptoms like flickering headlights or poor illumination, it's best to avoid driving until repairs are made.

How can I diagnose B0AD3 myself using GeekOBD APP?

To diagnose B0AD3 with GeekOBD APP, first connect the app to your vehicle's OBD-II port. Run a full scan to check for any diagnostic trouble codes, including B0AD3. Pay attention to freeze frame data that may show when the error occurred, and look for any related codes that could help pinpoint the issue.

What vehicles are most commonly affected by B0AD3?

DTC B0AD3 is frequently reported in the 2017-2020 Ford Explorer and Lincoln MKX models, where the Adaptive Front Lighting System is standard. Always check for any recalls or technical service bulletins related to your vehicle that might address this issue.

How can I prevent B0AD3 from happening again?

To prevent B0AD3 from recurring, perform regular inspections of your vehicle's lighting system, including checking for wiring damage and ensuring that headlight assemblies are properly aligned. Keeping software updated and promptly addressing any warning lights can also help maintain system integrity.

What is B0AD3?

The diagnostic trouble code (DTC) B0AD3 relates to the Adaptive Front Lighting System (AFS), which is designed to improve night visibility by adjusting the direction of the vehicle's headlights based on steering input. When this code triggers, it indicates that the AFS has detected a malfunction, possibly due to issues with its sensors or control modules. Commonly found in vehicles like the 2017-2020 Ford Explorer and Lincoln MKX, this code can lead to reduced visibility at night, making driving more hazardous. The system may not function correctly, causing the headlights to point inappropriately, which can severely affect nighttime driving safety. Ignoring this code can lead to further complications, including potential damage to the lighting system itself or increased repair costs down the line. Therefore, understanding the implications of DTC B0AD3 is crucial for maintaining safe and effective vehicle operation.

Symptoms

Common symptoms when B0AD3 is present:

  • The check engine light remains illuminated on your dashboard, indicating a fault in the vehicle's systems.
  • Headlights do not adjust during turns, resulting in poor visibility at night.
  • A noticeable decrease in night-time visibility, making it difficult to see the road clearly.
  • Unexpected flickering or failure of headlights while driving at night.
  • Error messages related to the lighting system appear on the vehicle's display.

Possible Causes

Most common causes of B0AD3 (ordered by frequency):

  1. The most common cause of DTC B0AD3 is a faulty AFS control module, which is responsible for interpreting data from the sensors—this accounts for about 60% of cases.
  2. Another likely cause is misalignment of the headlight assembly, which can happen due to physical impacts or wear and tear over time.
  3. Corroded or damaged wiring within the AFS circuit can lead to intermittent faults—regular inspections can help prevent this.
  4. Less common causes include sensor failures, such as the steering angle sensor, which can disrupt the AFS functionality.
  5. Rarely, software issues within the vehicle's onboard computer systems can trigger this code, necessitating a software update.
