What is B0957?

The B0957 diagnostic trouble code (DTC) indicates a malfunction in the airbag sensor system, specifically linked to the passenger or driver airbags. This code often arises due to a failure in the airbag control module or a faulty sensor. When this DTC triggers, it usually signifies that the airbag system is unable to properly communicate or function as designed, which could lead to airbags not deploying in the event of a collision, posing a serious safety risk. Additionally, this code can stem from issues like wiring problems, corroded connectors, or damaged sensor units. If you own a 2016-2021 Ford Explorer or a 2017-2020 Honda CR-V, be particularly vigilant for this code, as it has been reported frequently in these models. Ignoring this code might not only result in safety hazards but could also lead to costly repairs down the line, as the airbag system is critical for passenger safety. It's essential to address the B0957 code promptly to ensure that your vehicle's airbag system is functioning correctly, protecting you and your passengers in the event of an accident.

Symptoms

Common symptoms when B0957 is present:

  • The airbag warning light on your dashboard is illuminated, indicating a fault in the airbag system.
  • You may experience intermittent issues with the seat belt warning, suggesting a potential malfunction in the airbag system.
  • Inconsistent airbag system performance, where the airbag doesn't deploy during a test or simulation.
  • In some cases, the vehicle may exhibit issues with the safety restraint systems, leading to a lack of confidence in airbag performance.
  • You may also notice unusual electronic behavior in your vehicle's dashboard or infotainment system.

Possible Causes

Most common causes of B0957 (ordered by frequency):

  1. The most common cause of the B0957 code is a faulty airbag sensor, with a likelihood of about 60%. This can happen due to age, wear, or exposure to moisture.
  2. A second potential cause is damaged wiring or connectors, which can account for around 25% of cases. Corroded connections can disrupt the signal sent to the airbag control module.
  3. A third cause, although less common, is a malfunction in the airbag control module itself. Regular diagnostics can help prevent this by identifying issues early.
  4. Less common but serious causes include factory defects in specific vehicle models, which may require manufacturer recalls or technical service bulletins (TSBs) to address.
  5. A rare cause could be an after-market modification that interferes with the airbag system, leading to the B0957 code.
