What is B10D3?
The diagnostic trouble code (DTC) B10D3 pertains to an issue within the vehicle's body control module (BCM), specifically related to the driver's side door module. This code indicates that the BCM has detected an abnormal signal from the driver's door switch or the module itself has malfunctioned. When the B10D3 code is triggered, it can lead to various inconveniences such as the inability to lock/unlock the doors remotely, malfunctioning interior lights, or issues with the power windows. In real-world terms, this means your vehicle may not respond as expected when you try to operate these features, which can be frustrating and potentially unsafe. The BCM is responsible for managing various electronic functions in your vehicle, making it a crucial component. If ignored, this issue could lead to further electrical problems or even drain your vehicle's battery over time. For owners of specific models like the 2016-2020 Ford Explorer, understanding this DTC can help in diagnosing and addressing the related symptoms promptly to ensure your vehicle remains reliable.

Symptoms
Common symptoms when B10D3 is present:
- The check engine light or warning indicator for the door module remains illuminated on the dashboard, indicating an ongoing issue with the driver's door functionalities.
- Power door locks may not operate correctly, leading to difficulties in locking or unlocking the vehicle with the remote or the interior switch.
- Interior lights may malfunction, failing to turn on when the driver's door is opened, or they may stay on even when the door is closed, risking battery drain.
- The power window on the driver's side may become unresponsive or operate intermittently, causing frustration during use.
- In some cases, the vehicle's alarm system may activate unexpectedly due to a fault in the door module, causing unnecessary concern.
Possible Causes
Most common causes of B10D3 (ordered by frequency):
- The most common cause of the B10D3 code is a faulty driver's door module, accounting for approximately 60% of cases. This module may fail due to wear and tear or exposure to moisture.
- Another significant cause can be damaged wiring or connectors associated with the driver's door switch. This can happen due to physical stress or corrosion over time, which affects the signal transmission.
- A less common but notable cause is a malfunctioning body control module itself, which may misinterpret signals from the door module, leading to erroneous codes like B10D3.
- In rare cases, software issues within the BCM can cause this code to appear, necessitating a software update or reprogramming to resolve the conflict.
- Lastly, the presence of aftermarket accessories, such as alarm systems or remote starters, can interfere with the BCM's normal operation, triggering the B10D3 code.
