What is B08D5?

The diagnostic trouble code B08D5 typically indicates a malfunction in the vehicle's airbag system, specifically related to the side impact sensor or its circuit. This code is often triggered when the airbag control module detects an issue that could prevent the side airbags from deploying in a collision. Commonly seen in 2016 to 2020 Ford Explorers, the B08D5 code may be accompanied by other related codes that indicate similar issues. If your vehicle has this code, it's crucial to understand that it could impact the safety features of your car. The airbag system is designed to protect you and your passengers in the event of a crash, and a malfunction could mean that these safety measures will not activate when needed. It's essential to get this checked out as soon as possible, as driving with a malfunctioning airbag system can be extremely dangerous. The cause could range from a faulty sensor to damaged wiring or even a problem with the airbag control module itself. Addressing this code promptly not only ensures your safety but also prevents any further damage to the vehicle's safety system.

Symptoms

Common symptoms when B08D5 is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a malfunction in the airbag system.
  • You may notice that the side airbags do not deploy during a crash, which can lead to severe injury.
  • There might be intermittent functionality issues, where the side airbags sometimes function and sometimes don't, creating uncertainty about their reliability.
  • Unusual noises from the dashboard area when turning the ignition, indicating possible electrical issues related to the airbag system.
  • The vehicle may experience electrical faults, such as flickering lights or issues with other safety features, which could indicate a broader electrical problem.

Possible Causes

Most common causes of B08D5 (ordered by frequency):

  1. The most common cause is a faulty side impact sensor, which has a likelihood of about 50%. This sensor can fail due to wear and tear or exposure to moisture.
  2. Wiring issues, such as frayed wires or poor connections, account for around 30% of problems. These issues can occur due to vehicle accidents or corrosion.
  3. The airbag control module itself can fail, which is less common (about 15%), but it will require replacement and can be costly.
  4. Less common causes include software glitches in the vehicle's computer system, which can typically be resolved with a software update.
  5. Rare but possible causes include collision damage that affects the airbag system's integrity, requiring extensive repairs.
