What is B0D99?

The diagnostic trouble code (DTC) B0D99 indicates a potential issue with the vehicle's advanced driver-assistance systems (ADAS), often related to the vehicle's electronic control modules. This code is commonly found in 2016-2020 Ford Explorer models, but it can also appear in various other vehicles featuring similar technology. Specifically, B0D99 suggests a fault in the communication between the ADAS components, which can lead to impaired functionality of safety features like lane departure warnings, adaptive cruise control, and automatic emergency braking. For car owners, this means that while the vehicle may still operate, critical safety features could be compromised. Ignoring this code might not only affect driving safety but could also lead to more costly repairs down the line if the underlying issue is not addressed promptly. It's important to approach this code with a sense of urgency, as it directly impacts the reliability of your vehicle's advanced safety systems.

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

Symptoms

Common symptoms when B0D99 is present:

  • The check engine light may illuminate, indicating a problem with the vehicle's electronic systems.
  • Safety features like lane keeping assist or adaptive cruise control may become inoperative, leading to a lack of support in maintaining lane position or speed.
  • You might notice inconsistent performance of collision detection systems, potentially affecting safety during driving.
  • The vehicle may exhibit warning messages on the dashboard related to the ADAS features.
  • In some cases, you may experience erratic behavior in electronic systems, such as unexpected braking or acceleration.

Possible Causes

Most common causes of B0D99 (ordered by frequency):

  1. A malfunctioning ADAS control module is the most common cause, with a likelihood of around 60%. This could be due to software glitches or hardware failures.
  2. Wiring issues, such as damaged or corroded wires connecting the ADAS components, account for about 25% of cases. Regular inspections can help prevent this.
  3. Faulty sensors, particularly those involved in lane detection and collision avoidance, can contribute to this code. Preventive maintenance and timely replacement can mitigate risks.
  4. Less common causes include software updates that have not been applied, leading to incompatibilities within the vehicle's systems.
  5. In rare cases, interference from aftermarket electronic devices can create communication errors in the ADAS systems.
