What is B09D6?

The diagnostic trouble code (DTC) B09D6 indicates an issue with the Power Steering Control Module (PSCM). This module is crucial for the proper functioning of the electric power steering system in your vehicle. When this code appears, it often signals that the PSCM has detected a malfunction in the steering assist system, which may be due to communication errors, fault in the module itself, or issues related to the power steering motor. This can result in a loss of power steering assistance, making it difficult to steer your vehicle, especially at low speeds. Real-world implications include an increased risk of accidents due to impaired handling, as well as potential further damage to the steering system if not addressed promptly. Commonly found in 2015 to 2020 models of Ford Fusion and Lincoln MKZ, the B09D6 code can lead to various symptoms, including illuminated warning lights on the dashboard and unresponsive steering. Addressing this code quickly is important not only for safety but also for the longevity of your vehicle's steering components.

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

Symptoms

Common symptoms when B09D6 is present:

  • Check engine light and power steering warning light illuminate on the dashboard, indicating a potential steering issue.
  • Difficulty steering the vehicle, particularly at low speeds, leading to a feeling of heaviness or resistance when turning the wheel.
  • Unresponsive steering during low-speed maneuvers, making parking or navigating tight spaces particularly challenging.
  • Abnormal noises when steering, such as squeaking or grinding, indicating potential mechanical failure in the steering system.
  • Occasional loss of power steering assist altogether, requiring significant effort to steer.

Possible Causes

Most common causes of B09D6 (ordered by frequency):

  1. The most common cause of B09D6 is a faulty Power Steering Control Module (PSCM), accounting for about 60% of cases. This can happen due to wear and tear or electrical issues.
  2. Another prevalent cause is wiring issues, such as damaged or corroded connections in the steering system, which can create communication errors between components.
  3. A third cause may relate to the power steering motor itself, which can fail due to overheating or mechanical wear. Regular maintenance and checks can help prevent this.
  4. Less common but serious causes include software glitches in the PSCM that may require a reprogramming to resolve.
  5. Rarely, the issue could stem from a malfunction in the vehicle's battery or electrical system, which can affect the PSCM's performance.
