What is B067C?
The diagnostic trouble code B067C relates to an issue with the Body Control Module (BCM), which is a crucial component in managing various electronic functions in your vehicle, particularly those related to body systems. In vehicles like the 2015-2018 Chevrolet Silverado and GMC Sierra, the BCM is responsible for operations such as power windows, door locks, lighting, and even the vehicle's alarm system. When the B067C code is triggered, it typically indicates that the BCM has detected a fault in the system, often due to a communication error or an internal malfunction. This can lead to various electronic features becoming non-functional, which can be quite inconvenient and may compromise your vehicle's security. Ignoring this code may lead to further complications, including complete failure of electronic systems, which could require more extensive repairs. Therefore, understanding and addressing this issue promptly is essential for maintaining the functionality and safety of your vehicle.
