What is B0116?

DTC B0116 is a diagnostic trouble code that indicates an issue with the airbag system, specifically related to the driver’s airbag. This code often points towards a malfunctioning airbag module or issues with the wiring in the airbag circuit. When this code is triggered, it means that the airbag system has detected a fault that could prevent the airbag from deploying in the event of an accident, which poses a serious safety risk. In real-world terms, if you see this code on your vehicle’s OBD2 scanner, it’s critical to address it immediately. Ignoring the B0116 code could lead to severe consequences during a collision, as the airbags may not function as intended. It's essential for vehicle safety that all airbag systems are operational and free from faults. Common symptoms associated with this code include the airbag warning light being illuminated on the dashboard. In addition, the vehicle's safety features may be compromised, leading to increased risk during a crash. Addressing this issue promptly can help ensure your vehicle remains safe for you and your passengers.

Symptoms

Common symptoms when B0116 is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a fault in the airbag system.
  • You may notice that the seatbelt pretensioners do not operate correctly, which could affect occupant safety during a crash.
  • In some cases, the vehicle may exhibit erratic behavior such as delayed responses in the airbag system, posing further safety risks.
  • There may be an audible alert or chime signaling an issue with the airbag system.
  • You could experience a lack of feedback from the airbag system during vehicle diagnostics, making it difficult to assess other potential issues.

Possible Causes

Most common causes of B0116 (ordered by frequency):

  1. The most common cause of B0116 is a faulty airbag control module, responsible for managing the deployment of airbags, with a likelihood of around 40%.
  2. Another frequent cause is damaged wiring or connectors in the airbag circuit, which can occur due to wear and tear or accidents, contributing to about 30% of cases.
  3. A third potential cause could be a defective driver’s airbag itself, which may have manufacturing faults leading to deployment failure; preventive maintenance checks can help identify this.
  4. Less common but serious is the presence of corrosion in electrical connections, which can disrupt the airbag system's function.
  5. A rare cause could be software issues in the vehicle's onboard computer that might require reprogramming or updates.
