What is B106C?
The B106C diagnostic trouble code indicates a problem with the vehicle's body control module (BCM) related to the driver's seat position sensor. This code is commonly found in various vehicles, particularly in 2015-2019 Ford F-150 models and 2016-2019 Chevrolet Silverado trucks. When the B106C code is triggered, it means that the BCM is receiving an incorrect signal from the seat position sensor, which could lead to improper adjustment of the driver's seat. This issue can affect comfort, driving position, and even safety features like airbags, which may not deploy correctly if the seat is not positioned properly. Ignoring this code can lead to further complications, including a complete failure of the seat adjustment mechanism. Additionally, the check engine light may illuminate, and other related codes could appear, complicating the diagnostic process. Therefore, understanding and addressing the B106C code promptly is essential to maintaining your vehicle's safety and functionality.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B106C is present:
- The check engine light is illuminated, indicating a potential issue with the seat position sensor.
- Inability to adjust the driver's seat, leading to discomfort during driving.
- Airbag warning light may also appear, suggesting a possible impact on safety features.
- Unusual noises when attempting to adjust the seat, which may indicate a mechanical failure.
- Inconsistent seat position memory settings, causing the seat to revert to a previous position unexpectedly.
Possible Causes
Most common causes of B106C (ordered by frequency):
- The most common cause is a faulty seat position sensor, which has a likelihood of about 60%. This sensor may fail due to wear and tear or electrical issues.
- Another common cause is damaged wiring or connectors in the seat adjustment mechanism, which can result in poor electrical connectivity.
- Corrosion at the connectors can lead to intermittent signals, thus triggering the B106C code. Regular maintenance can prevent this issue.
- A less common but serious cause is a malfunctioning BCM itself, which may require reprogramming or replacement.
- In rare cases, issues with the power supply to the BCM can trigger this code, often due to blown fuses or faulty relays.
