C0B6C is frequently seen in 2016-2021 Chevrolet and GMC models. Owners should check for any recalls or Technical Service Bulletins (TSBs) related to the BCM for their specific vehicle.
How can I prevent C0B6C from happening again?
Regular maintenance, including inspecting wiring and connectors, updating software, and ensuring the BCM is protected from moisture, can help prevent future issues related to C0B6C.
What is C0B6C?
DTC C0B6C is a diagnostic trouble code that indicates a problem with the vehicle's Body Control Module (BCM) or a related system. This code is commonly associated with various makes and models, particularly in the 2016-2021 Chevrolet and GMC vehicles. When this code is triggered, it typically signifies that the BCM has detected an internal fault, which could lead to a range of issues including malfunctioning lights, windows, or door locks. In real-world terms, this means that essential functions controlled by the BCM may not operate correctly, impacting both convenience and safety. Drivers may notice symptoms such as flickering lights, inoperative power windows, or issues with the vehicle's central locking system. Ignoring this code can lead to more significant electrical problems and could potentially affect other systems in the vehicle. It's crucial to address DTC C0B6C promptly to ensure your vehicle remains safe and reliable. Regular maintenance and early diagnosis can prevent costly repairs later on.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0B6C is present:
- The check engine light stays on constantly, indicating a persistent issue with the BCM.
- Power windows may malfunction, either failing to operate or working intermittently, which can be frustrating for daily use.
- Central locking system may not respond as expected, leading to security concerns and inconvenience.
- Flickering interior or exterior lights, which can be distracting and may lead to safety issues while driving.
- Dashboard warning lights may illuminate unexpectedly, signaling electrical faults that could affect vehicle operation.
Possible Causes
Most common causes of C0B6C (ordered by frequency):
- The most common cause is a faulty Body Control Module, which has a likelihood of about 60%. This can occur due to age, exposure to moisture, or electrical surges.
- Another frequent cause is damaged wiring or connectors related to the BCM, which can lead to poor connections and intermittent faults.
- A third cause could be software issues within the BCM, which are often preventable through regular updates and maintenance checks.
- Less common but serious causes include short circuits in the electrical system, which can lead to extensive damage if not addressed.
- A rare cause could be a factory defect in the BCM itself, which may require replacement under warranty if identified early.
