What is C0B64?
DTC C0B64 indicates an issue with the Body Control Module (BCM), particularly related to the communication with the vehicle's electrical systems. This code is often found in popular models such as the 2016-2019 Honda Civic and the 2017-2020 Toyota Camry. When the BCM detects a malfunction, it triggers this code to alert the driver. The BCM is responsible for managing various electronic functions, including interior lighting, door locks, and security systems. If C0B64 appears, it may indicate a failure in one of these systems or a communication breakdown within the BCM. Ignoring this code could lead to further electrical issues and may affect vehicle safety features such as anti-theft systems and central locking mechanisms. It’s crucial to address this code promptly to ensure the functionality of your vehicle's electronic systems. If you're experiencing issues with your vehicle's lights, locks, or other electronic features, this may be a direct result of the BCM malfunctioning, which can lead to more serious problems down the road if not rectified.
