To prevent B0C4E from recurring, regularly check and maintain your power steering fluid levels, inspect wiring for wear or damage, and keep up with software updates from your dealership.

What is B0C4E?

The diagnostic trouble code (DTC) B0C4E indicates a malfunction within the power steering control module, specifically related to the steering assist feature. This code is primarily seen in various Ford models manufactured between 2015 and 2019, including the Ford F-150 and Ford Explorer. When this code is triggered, it typically signifies that the vehicle's power steering system is experiencing an issue that could lead to reduced steering assist or complete loss of steering assistance. This can manifest as a heavier steering feel, making it difficult for the driver to steer, especially at low speeds. In essence, the B0C4E code serves as a warning that the power steering system requires immediate attention to ensure vehicle safety. A faulty power steering control module can lead to increased wear on components, and if left unchecked, it may result in more significant repairs, potentially costing hundreds of dollars. Understanding this code and addressing it promptly is crucial for maintaining vehicle performance and ensuring a safe driving experience.

Symptoms

Common symptoms when B0C4E is present:

  • The check engine light illuminates, indicating a fault in the power steering system.
  • Drivers may notice that the steering feels unusually heavy, particularly when turning at low speeds, indicating reduced power assist.
  • Increased effort is required to steer the vehicle, especially during parking maneuvers, which can lead to driver fatigue.
  • Inconsistent steering response can occur, where the vehicle may not react as expected when turning, posing a safety risk.
  • Occasional steering system failures may be experienced, where the steering assist temporarily cuts out, making the vehicle difficult to control.

Possible Causes

Most common causes of B0C4E (ordered by frequency):

  1. The most common cause of the B0C4E code (approximately 60% likelihood) is a faulty power steering control module. This module can fail due to electrical issues or internal component failure, leading to a loss of power assist.
  2. Another prevalent cause is wiring issues or poor connections in the power steering circuit, which can account for about 25% of cases. Corrosion or frayed wires can disrupt communication between the control module and the steering system.
  3. A third potential cause is low power steering fluid levels or contamination, which can affect the hydraulic assist. Regular fluid checks and maintenance can help prevent this issue.
  4. Less commonly, software glitches in the vehicle's onboard computer may trigger the code. These can sometimes be resolved with a simple software update.
  5. Rarely, a malfunctioning steering rack itself may lead to the B0C4E code, requiring more extensive repairs and potentially driving up costs.
