What is B106D?

DTC B106D is a diagnostic trouble code that indicates an issue with the vehicle's body control module (BCM) related to the driver's door module. This code often appears when there is a malfunction detected in the circuit that controls the power windows, door locks, and other features associated with the driver's door. When this code triggers, it can lead to several inconveniences, such as failure to operate the power windows or locks, creating a safety concern and affecting overall vehicle functionality. The body control module is crucial for managing various electronic components in the vehicle, so a B106D code often signifies potential electrical or wiring issues. It's important for vehicle owners to address this code promptly, as ignoring it may lead to more severe electrical problems or additional codes appearing in the system. If you own a vehicle like the 2015 Honda Civic, it’s essential to understand that this code could result from a simple wiring issue or a more complex BCM failure, which could lead to higher repair costs. Seeking professional diagnostics is recommended to ascertain the exact nature of the problem and to ensure that all systems are functioning correctly. Ignoring the B106D code could lead to further complications down the road, including safety risks and increased repair bills.

Symptoms

Common symptoms when B106D is present:

  • The check engine light stays illuminated, indicating a persistent issue that needs attention.
  • Power windows on the driver's side might not function, leaving you unable to open or close them.
  • The door locks may fail to respond, preventing you from locking or unlocking the driver's door.
  • You may notice flickering lights on the dashboard, which can indicate electrical problems related to the BCM.
  • The vehicle's alarm system might activate unexpectedly, suggesting a malfunction in the door module.

Possible Causes

Most common causes of B106D (ordered by frequency):

  1. The most common cause is a faulty driver's door module, with a likelihood of around 60%. This can occur due to wear and tear or exposure to moisture.
  2. Another frequent cause is damaged wiring in the driver's door harness, which can lead to shorts or open circuits. This typically happens in older vehicles or those exposed to harsh conditions.
  3. Corrosion in connectors can also cause the B106D code, often seen in vehicles that have undergone extensive weather exposure. Regular maintenance can help mitigate this issue.
  4. A malfunctioning body control module itself can be a serious cause, though less common, accounting for about 10%. This may require a more expensive replacement.
  5. Lastly, a rare occurrence could be related to software issues within the BCM, which may need a software update or reprogramming.
