What vehicles are most commonly affected by B08AC?

The B08AC code is commonly found in vehicles like the 2015-2019 Ford F-150 and some other Ford models. Checking for any recalls or technical service bulletins (TSBs) related to your specific model can provide further insight.

How can I prevent B08AC from happening again?

To prevent the B08AC code from recurring, ensure regular maintenance of your power steering system. This includes checking fluid levels, inspecting wiring for damage, and keeping software updated. Regularly using diagnostic tools like the GeekOBD APP can also help catch issues early.

What is B08AC?

DTC B08AC is a diagnostic trouble code that indicates a problem with the vehicle's power steering control module or associated wiring. Specifically, this code is often seen in vehicles like the 2015-2019 Ford F-150, where the power steering system may not function correctly. This can lead to difficulties in steering, making it harder to maneuver the vehicle, especially at low speeds or during parking. The code may trigger when the steering angle sensor detects an unusual signal, leading the vehicle's onboard computer to alert the driver. It's crucial to address this issue promptly, as ignoring it can lead to more severe steering problems and even pose safety risks on the road. Drivers might notice that the steering feels stiffer than usual or that warning lights illuminate on the dashboard. Depending on the severity of the issue, it may also affect the overall driving experience, making long drives less comfortable.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B08AC is present:

  • Check engine light illuminated on the dashboard, indicating a potential issue that needs attention.
  • Loss of power steering assist, making it noticeably more difficult to steer, especially at low speeds.
  • Unusual noises when turning the steering wheel, such as grinding or whining sounds.
  • Steering wheel shaking or vibrating, which can indicate underlying mechanical issues.
  • Erratic steering response, where the vehicle may not respond accurately to steering input.

Possible Causes

Most common causes of B08AC (ordered by frequency):

  1. The most common cause of the B08AC code is a faulty power steering control module, which has a likelihood of about 60%. This electronic component is responsible for regulating the power steering system's assist levels.
  2. Another prevalent cause is damaged or frayed wiring in the power steering system, which can disrupt communication between the control module and the steering components.
  3. A failing steering angle sensor is another possibility; this sensor measures the angle of the steering wheel and sends data to the power steering module. If it fails, it can trigger the B08AC code. Regular checks and calibration can help prevent this.
  4. Less commonly, a software glitch in the vehicle's onboard computer can lead to erroneous codes. Keeping your vehicle's software updated is essential to minimize these issues.
  5. Finally, hydraulic fluid leaks in vehicles using hydraulic power steering systems can also cause steering issues, although this is less common in newer vehicles that predominantly use electric steering.
