What is B0B47?
The B0B47 diagnostic trouble code indicates a communication error between the power steering control module and the vehicle's onboard computer systems. This code typically arises in vehicles equipped with electric power steering (EPS) systems, where the power steering control module is responsible for interpreting steering input and adjusting assistance accordingly. In practical terms, when this code is triggered, drivers may experience reduced power steering assistance, making the steering feel heavier or unresponsive, particularly at low speeds or during parking maneuvers. The issue can stem from various factors, including faulty wiring, corroded connectors, or a malfunctioning power steering control module itself. If left unresolved, a B0B47 code may lead to increased difficulty in steering, particularly in tight situations, which can pose safety risks. This code is prevalent in models such as the 2015-2020 Ford F-150 and other vehicles that utilize electric power steering systems. Understanding this code is crucial for car owners as it directly impacts steering performance and overall vehicle safety.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0B47 is present:
- The check engine light may illuminate, indicating an issue with the vehicle's systems.
- Drivers may feel a noticeable increase in steering effort, especially at low speeds or while parking.
- There may be intermittent loss of power steering assistance, leading to unpredictable steering response.
- In some cases, a warning message may appear on the dashboard regarding power steering.
