What is B0384?
DTC B0384 is a diagnostic trouble code that indicates a problem with the Body Control Module (BCM) performance. This code is particularly prevalent in vehicles such as the 2013-2018 Ford Escape and 2014-2019 Chevrolet Silverado. The BCM is a crucial part of your vehicle's electrical system, responsible for controlling various electronic components like lights, windows, and door locks. When B0384 is triggered, it typically means that the BCM has detected a malfunction in its internal performance or is unable to communicate effectively with other modules. This can lead to a range of symptoms, including electrical gremlins in your vehicle, such as lights flickering or inoperable accessories. Ignoring this code can lead to larger electrical system issues, impacting vehicle safety and functionality. Therefore, it’s crucial to address this error promptly to ensure a safe and reliable driving experience.
