What is B0C64?
The DTC B0C64 is a diagnostic trouble code that indicates a fault related to the vehicle's body control module, specifically regarding the rear control module's communication with other systems. This issue can manifest in various ways, affecting the vehicle's lighting, electrical components, and overall functionality. In simpler terms, this code suggests that the rear control module is experiencing difficulties in executing its commands or communicating effectively with the body control module. For example, if you're driving a 2017 Ford Explorer and see the check engine light illuminated along with this code, it might signal problems with your rear lights, power door locks, or even the climate control settings. Ignoring this issue can lead to further electrical failures and could potentially affect safety features like brake lights or turn signals. Therefore, addressing a B0C64 code promptly is crucial for ensuring the vehicle operates safely and efficiently. If you’re experiencing unusual electrical behavior in your vehicle, it's wise to investigate the cause of this code as it can lead to more serious issues if left unresolved.
