Using the GeekOBD APP, you can perform a thorough scan of your vehicle's onboard diagnostics. Look for the B0059 code and review any additional codes that may be present. Pay attention to freeze frame data for context on when the error occurred, and check for any ongoing symptoms.

What vehicles are most commonly affected by B0059?

Vehicles like the 2010-2015 Ford Fusion and similar models from manufacturers like Mazda and Lincoln are frequently affected by code B0059. It's advisable to check for any recalls or Technical Service Bulletins (TSBs) related to the airbag system in your specific vehicle.

How can I prevent B0059 from happening again?

Regular maintenance of your vehicle's electrical systems can help prevent B0059. Ensure that all connections are clean and free from corrosion, and consider having the airbag system inspected during annual vehicle service to catch any issues early.

What is B0059?

The diagnostic trouble code B0059 indicates a fault in the airbag sensor circuit, specifically related to the driver's side airbag. This code can trigger the airbag warning light on your dashboard, indicating a potential malfunction in the airbag system. When this occurs, the vehicle's safety measures may be compromised, which could have serious implications in the event of an accident. The airbag system relies on a series of sensors and circuits to function correctly, and if any of these components fail, it can result in the airbags not deploying as they should during a crash. This code is often associated with issues such as damaged wiring, faulty sensors, or poor connections within the airbag system. If you own a vehicle, particularly models like the 2010-2015 Ford Fusion, it's crucial to address this code promptly to ensure your safety and that of your passengers. Ignoring this code can lead to costly repairs down the line and jeopardize the effectiveness of your airbag system. If the airbag light is illuminated, it's a clear signal that you should seek professional diagnostics and repair as soon as possible.

Symptoms

Common symptoms when B0059 is present:

  • Airbag warning light stays illuminated on the dashboard, indicating a potential issue with the airbag system.
  • Inconsistent airbag deployment during crash simulations, which may not trigger during testing if the system is malfunctioning.
  • Unusual noises from the driver's side dashboard area, possibly indicating a faulty sensor or wiring issue.
  • Increased diagnostic trouble codes related to the airbag system when scanned with an OBD2 tool like GeekOBD APP.
  • Warning chimes that may sound intermittently, alerting the driver to a malfunction in the airbag system.

Possible Causes

Most common causes of B0059 (ordered by frequency):

  1. The most common cause of code B0059 is a defective airbag sensor, which accounts for about 50% of cases. This can happen due to wear and tear or physical damage to the sensor.
  2. Another frequent cause is damaged wiring or connectors, with a likelihood of 30%. Corrosion or frayed wires can disrupt the electrical connection necessary for the airbag system.
  3. Poor ground connections can also trigger this code, with about 15% of cases resulting from inadequate grounding that affects sensor performance and reliability.
  4. Less common, but serious causes include issues with the airbag control module itself, which can lead to complete failure of the airbag system.
  5. A rare cause might be a software glitch in vehicles equipped with advanced airbag systems, affecting their ability to communicate properly.
