What is B08CB?
The DTC B08CB is a diagnostic trouble code that indicates a malfunction within the Body Control Module (BCM) of your vehicle. This code typically appears in vehicles such as the 2016-2020 Ford Explorer, indicating that the BCM has detected an issue with a specific circuit or component related to body control functions. The BCM is responsible for controlling various electronic systems within the vehicle, including lighting, power windows, and security features. When this code is triggered, it means there may be a fault in the wiring, a malfunctioning component, or an issue with the BCM itself. As a result, you might experience problems such as inoperative lights, non-functioning power windows, or issues with your vehicle's keyless entry system. Ignoring this code can lead to further electrical failures, making it crucial to address any underlying issues as soon as possible. If you're experiencing any related symptoms, such as flickering lights or malfunctioning accessories, it's advisable to diagnose and repair the issue promptly to maintain the vehicle's functionality and safety.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B08CB is present:
- Check engine light remains illuminated, indicating potential electronic issues.
- Inoperative power windows, which might fail to respond to driver input.
- Flickering or malfunctioning interior lights, making it difficult to see inside the vehicle.
- Keyless entry may not function properly, causing inconvenience when trying to unlock or start the vehicle.
- Inconsistent operation of other electronic accessories, such as the radio or dashboard lights.
Possible Causes
Most common causes of B08CB (ordered by frequency):
- Faulty Body Control Module (BCM) – Likely the root cause, with a 40% chance of occurrence. The BCM may fail due to electrical surges or water damage.
- Damaged wiring or connectors – Occurs in about 30% of cases; frayed wires or poor connections can disrupt communication between the BCM and other components.
- Corrosion in the BCM connectors – A 20% likelihood; moisture can cause rust and corrosion, leading to electrical failures. Regular inspections can help prevent this.
- Short circuits in related components – Less common but serious, with a 5% chance; components like switches might short, leading to BCM errors.
- Software glitches in the BCM – Rare but possible, with a 5% likelihood; periodic updates or resets might be necessary to resolve software issues.
