Common Questions
What does B0C6A mean and how does it affect my car?
B0C6A indicates a performance issue with your vehicle's Body Control Module (BCM). This can lead to various electronic components, like lights and locks, malfunctioning. If not addressed, it could result in safety concerns and affect your driving experience.
What are the most common causes of B0C6A and how much does it cost to fix?
Common causes include a faulty BCM, poor electrical connections, and software glitches. Repair costs can range from $50 for connection repairs to $800 for BCM replacement, depending on the issue found.
Can I drive my car with B0C6A or should I stop immediately?
It's advisable to avoid driving your vehicle if you see the B0C6A code. While you may be able to drive short distances, this code indicates potential failures in critical electronic systems, which could lead to safety issues.
How can I diagnose B0C6A myself using GeekOBD APP?
With the GeekOBD APP, start by scanning for DTCs. Look for B0C6A and any additional codes. Analyze freeze frame data for context, and check real-time data for the BCM to see if it responds to commands.
What vehicles are most commonly affected by B0C6A?
The B0C6A code commonly affects models like the 2017-2020 Ford Focus and the 2018-2021 Chevrolet Malibu, among others. Always check for any recalls or technical service bulletins related to your vehicle.
How can I prevent B0C6A from happening again?
Regular maintenance of electrical systems, ensuring connections are clean and secure, and timely software updates can help prevent B0C6A from recurring.
What is B0C6A?
The diagnostic trouble code (DTC) B0C6A indicates a performance issue with the Body Control Module (BCM). This module is crucial as it oversees various electronic components within the vehicle, including lighting, power windows, and door locks. When the BCM detects an abnormality in its performance or cannot communicate with other control modules, it triggers the B0C6A code. This can lead to a variety of symptoms such as malfunctioning lights or unresponsive electronic features. The implications can range from minor inconveniences, like a door lock that won’t operate, to significant safety concerns if critical systems fail. Car owners should take this code seriously, as ignoring it might lead to further electrical issues or even vehicle immobilization. The BCM is the brain for many electronic functions in your vehicle, and ensuring it operates correctly is essential for safe and reliable vehicle operation.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0C6A is present:
- The check engine light remains illuminated, indicating a persistent issue with the BCM.
- Power windows may operate inconsistently, sometimes failing to respond or working intermittently.
- Exterior lights flicker or fail to operate, affecting visibility at night and potentially compromising safety.
- Unresponsive door locks, which may fail to lock or unlock reliably, posing a security risk.
- Dashboard warning lights illuminate unexpectedly, indicating possible electrical malfunctions.
Possible Causes
Most common causes of B0C6A (ordered by frequency):
- The most common cause is a faulty Body Control Module, which can occur in about 60% of cases. This may happen due to manufacturing defects or wear and tear over time.
- Another cause could be poor electrical connections, often due to corrosion or loose wiring, affecting around 25% of cases. Regular maintenance can help prevent this issue.
- A third cause may involve software glitches within the BCM, which can occur in 10% of cases. Performing software updates can often resolve this.
- Less common but serious is damage from water intrusion, which can affect the BCM and is more likely in vehicles exposed to heavy rain or flooding.
- A rare cause could be a failing alternator, which can cause voltage fluctuations and affect BCM performance.

Diagnostic Steps
Professional B0C6A Diagnosis Process
Follow these systematic steps to accurately diagnose B0C6A. 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 (5-10 minutes)
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion (5-10 minutes). Look for any visible wear around the BCM and its connectors.
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). Ensure that you note any additional codes that may help identify the root cause.
Step 3: Step 3: Component testing - Use a multimeter to test voltage and ground at the BCM harness
Step 3: Component testing - Use a multimeter to test voltage and ground at the BCM harness. This should take about 20-30 minutes, allowing you to check for proper functionality.
Step 4: Step 4: System function test - After any repairs, verify proper operation by cycling the affected systems and clearing codes (10-15 minutes)
Step 4: System function test - After any repairs, verify proper operation by cycling the affected systems and clearing codes (10-15 minutes). Make sure all systems controlled by the BCM are functioning as expected.
Step 5: Step 5: Road test verification - Drive the vehicle under various conditions to confirm repair success (15-20 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm repair success (15-20 minutes). Pay attention to any intermittent issues that may arise during different driving scenarios.
