What is B03E6?

The Diagnostic Trouble Code (DTC) B03E6 typically indicates an issue with the vehicle's Automatic Emergency Braking (AEB) system, particularly in models like the 2016-2019 Ford Edge. This code signifies that the AEB system has detected a malfunction in its sensors or control module. The AEB system is crucial for enhancing safety by automatically applying the brakes if a collision is imminent, helping prevent accidents. When the B03E6 code is triggered, it may lead to a lack of confidence in the vehicle's ability to avoid a collision, posing a significant safety risk. Drivers may also notice that the AEB warning light illuminates on the dashboard. It's important to address this issue promptly, as ignoring it can lead to reduced functionality of crucial safety systems. The underlying problem can range from simple sensor misalignments to more complex control module failures, necessitating accurate diagnosis and repair to restore full AEB functionality.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B03E6 is present:

  • The AEB warning light is illuminated on the dashboard, indicating a malfunction in the braking system.
  • The vehicle may experience erratic braking behavior, where the brakes may apply unexpectedly or fail to respond as needed during critical moments.
  • Drivers may notice a decrease in overall vehicle safety features, making it less reliable in preventing collisions.
  • Increased feedback from the vehicle's stability control system, which may cause abnormal handling in certain conditions.
  • Possible error messages displayed on the vehicle's infotainment system regarding the AEB functionality.

Possible Causes

Most common causes of B03E6 (ordered by frequency):

  1. The most common cause is a misaligned or faulty AEB sensor, which has a likelihood of about 60%. This can happen due to physical damage or improper installation.
  2. Another frequent cause is a failed AEB control module, which processes information from the sensors. This has a likelihood of around 25%, often requiring replacement.
  3. Wiring issues such as frayed or corroded connections can lead to intermittent signals, comprising about 10% of cases. Regular inspections can help prevent this.
  4. Less common but serious causes include software glitches in the AEB system, which might require a software update or reprogramming to resolve.
  5. A rare cause could be environmental factors like ice or dirt obstructing the sensor's line of sight, which can be easily checked and cleaned.
