To diagnose B0D47 using the GeekOBD APP, connect the app to your vehicle's OBD2 port, perform a full scan to retrieve all error codes, and analyze freeze frame data for context. Look for related codes that might indicate the root cause of the B0D47.
What vehicles are most commonly affected by B0D47?
B0D47 is frequently reported in 2015-2020 models from General Motors, Ford, and Chrysler. It’s advisable to check for any recalls or Technical Service Bulletins (TSBs) related to steering issues in these vehicles.
How can I prevent B0D47 from happening again?
Regular maintenance of your vehicle’s electrical systems and steering components is key. Ensure connections are clean and secure, monitor for any steering performance changes, and promptly address any warning lights that appear.
What is B0D47?
The diagnostic trouble code (DTC) B0D47 indicates a malfunction in the vehicle's body control module (BCM) related to the electronic power steering (EPS) system or another critical function. This code is commonly seen in a variety of vehicles, particularly those manufactured by General Motors, Ford, and Chrysler between 2015 and 2020. When this code is triggered, it means that the BCM has detected an issue that could affect the vehicle's steering or other electronic systems. Drivers may experience issues such as difficulty in steering, intermittent loss of power steering assist, or even a complete failure of the EPS system in severe cases. It's important to address this code promptly to avoid potential safety hazards while driving. Ignoring this code could lead to more extensive damage, increased repair costs, and compromised vehicle safety. If you notice the check engine light illuminated alongside other symptoms, it’s advisable to have your vehicle inspected by a qualified technician who can perform a thorough diagnostic. Understanding the implications of code B0D47 will help you make informed decisions regarding repairs and maintenance, ensuring your vehicle remains safe and dependable on the road.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0D47 is present:
- Check engine light stays on constantly, indicating a persistent issue with the BCM or EPS.
- Difficulty steering or reduced power steering assist, making the vehicle harder to control especially at low speeds.
- Unusual noises from the steering column, such as whining or grinding, that may indicate mechanical issues.
- Intermittent loss of steering assist, where the power steering may work sporadically, creating unpredictable handling.
- Increased fuel consumption due to the additional strain on the engine if the steering system is malfunctioning.
Possible Causes
Most common causes of B0D47 (ordered by frequency):
- Faulty body control module (BCM) - This is the most common cause, accounting for approximately 60% of cases. The BCM may fail due to electrical issues, corrosion, or software problems.
- Wiring issues - Damaged or corroded wiring connections related to the EPS system may lead to communication failures between the BCM and the power steering motor.
- Sensor failures - Malfunctioning sensors that provide data to the BCM can trigger the B0D47 code, especially if they provide incorrect readings.
- Electronic power steering motor failure - A less common but serious cause, where the EPS motor itself may fail due to wear or manufacturing defects, requiring replacement.
- Software glitches - Occasionally, outdated or corrupted software in the BCM can result in erroneous codes, necessitating a software update.
