What vehicles are most commonly affected by B0C6D?
This code is frequently seen in the 2016-2020 Ford Explorer, but can also affect other Ford models within the same production years, including the Edge and Fusion.
How can I prevent B0C6D from happening again?
Regular maintenance, including checking electrical connections and keeping the vehicle dry, can help prevent BCM issues. Additionally, ensuring software updates are performed can mitigate potential glitches.
What is B0C6D?
The diagnostic trouble code (DTC) B0C6D indicates a malfunction within the Body Control Module (BCM) in vehicles such as the 2016-2020 Ford Explorer and select other models. This code is typically triggered when the BCM detects an internal fault or incorrect data communication. The BCM is crucial for various vehicle functions, controlling systems ranging from lighting and wipers to security features and power windows. When B0C6D is active, drivers may experience multiple electrical issues, including malfunctioning accessories or erratic behavior of electronic components. This issue can lead to increased repair costs if not addressed promptly, as the BCM controls many interconnected systems. It’s important for car owners to understand that this code signifies a problem that could potentially impact vehicle safety and performance. Ignoring this issue may result in further complications, requiring more extensive repairs, and can even lead to a no-start condition in severe cases. Therefore, it’s recommended to diagnose and resolve the underlying problems as soon as possible to maintain vehicle reliability and safety.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0C6D is present:
- The check engine light activates, and may remain illuminated.
- Power windows or locks may malfunction, working intermittently.
- Interior lights may flicker or fail to operate as expected.
- The vehicle may exhibit issues with the ignition system, potentially causing difficulty starting.
- Erratic behavior of other electronic components, such as the radio or dashboard displays.
Possible Causes
Most common causes of B0C6D (ordered by frequency):
- The most common cause is a faulty Body Control Module itself, which occurs in about 60% of cases. This can result from internal component failure due to age or manufacturing defects.
- Another frequent cause is damaged wiring or connectors linked to the BCM, accounting for approximately 20% of cases. Corrosion or wear can lead to poor connections and faulty signals.
- A third cause could be software issues or glitches in the vehicle’s electronic systems, which can be addressed through updates or reprogramming.
- Less common but serious causes include water intrusion into the BCM, which can cause significant damage and is often due to poor sealing or a faulty windshield.
- A rare cause might be a failure in the vehicle’s CAN bus (Controller Area Network) system, which could affect communication between the BCM and other control modules.

Diagnostic Steps
Professional B0C6D Diagnosis Process
Follow these systematic steps to accurately diagnose B0C6D. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion around the BCM (5-10 minutes)
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion around the BCM (5-10 minutes).
Step 2: Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes)
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes).
Step 3: Step 3: Component testing - Use a multimeter to check the BCM's power and ground connections, and test suspected components for proper function (20-30 minutes)
Step 3: Component testing - Use a multimeter to check the BCM's power and ground connections, and test suspected components for proper function (20-30 minutes).
Step 4: Step 4: System function test - Verify the operation of systems controlled by the BCM after repairs and clear codes (10-15 minutes)
Step 4: System function test - Verify the operation of systems controlled by the BCM after repairs and clear codes (10-15 minutes).
