What is B058A?

DTC B058A refers to a specific diagnostic trouble code that indicates a problem with the vehicle's restraint system, particularly related to the driver’s airbag system. This code is often triggered when the vehicle's onboard diagnostic system detects that there is an issue with the airbag deployment circuits or the safety restraint system itself. Commonly found in vehicles like the 2015-2019 Ford F-150, B058A can lead to the airbag light illuminating on your dashboard and may prevent the airbag from deploying in the event of a collision, posing serious safety risks. The implications of this code are significant as they directly affect the safety of the driver and passengers. If this code appears, it is essential to address it quickly to ensure that the airbag system functions correctly. Ignoring this code can result in expensive repairs down the line and compromises your vehicle’s safety features, making it crucial for vehicle owners to understand and rectify the underlying issues as soon as possible.

Symptoms

Common symptoms when B058A is present:

  • The airbag warning light remains illuminated on the dashboard, indicating an issue with the airbag system.
  • The vehicle may experience occasional electrical faults, such as malfunctioning seatbelt indicators or unresponsive dashboard lights.
  • In some cases, you might notice that the airbag does not deploy during a crash test or simulation, showcasing a critical safety risk.
  • Drivers may report a noticeable delay in the deployment of the airbag system during testing.
  • In specific scenarios, a buzzing or warning chime may sound intermittently, signaling a problem with the airbag system.

Possible Causes

Most common causes of B058A (ordered by frequency):

  1. A faulty airbag control module is the most common cause of the B058A code, with a likelihood of around 40%. This module is responsible for monitoring the airbag system and can fail due to age or water damage.
  2. Damaged wiring or poor connections in the airbag deployment circuits can account for about 30% of cases. Over time, these wires may corrode or become loose, leading to communication failures.
  3. A malfunctioning impact sensor is another potential cause, which can trigger the B058A code. Preventive measures include regular inspections of the airbag system during vehicle maintenance.
  4. Less common but serious causes include severe vehicle accidents that may physically damage the airbag system or its components, impacting safety.
  5. Rarely, software issues in the vehicle's onboard computer can trigger this code, requiring a software update or reset to resolve the problem.
