Common Questions
What does B107E mean and how does it affect my car?
The B107E code points to a problem in the Body Control Module (BCM), which manages multiple electronic systems in your vehicle. If this code appears, you might notice issues with lights, locks, or other accessories that rely on the BCM. Addressing this promptly is critical to prevent worsening electrical issues.
What are the most common causes of B107E and how much does it cost to fix?
Common causes of B107E include wiring shorts (50% likelihood), faulty BCMs, and corrosion at connectors. Repairs can range from $100 for wiring fixes to $600 for BCM replacement, depending on the problem.
Can I drive my car with B107E or should I stop immediately?
While you may still drive your vehicle, it's not advisable to ignore the B107E code. Continued operation can lead to more significant electrical issues that may compromise your vehicle's safety and functionality.
How can I diagnose B107E myself using GeekOBD APP?
Using the GeekOBD APP, you can scan your vehicle for diagnostic codes, view freeze frame data for context, and perform live data monitoring to identify issues with the BCM and related components.
What vehicles are most commonly affected by B107E?
Common vehicles affected by the B107E code include the 2015-2018 Honda Civic, 2016-2019 Toyota Corolla, and various Ford models from 2013-2018. It's good to check for any recalls or technical service bulletins related to BCM issues for your specific model.
How can I prevent B107E from happening again?
Regular maintenance, such as inspecting wiring and connectors for corrosion and wear, can help prevent B107E. Additionally, ensuring your vehicle's electrical systems are functioning correctly and updating software as needed may also reduce the risk.
What is B107E?
The DTC B107E code indicates a malfunction within the Body Control Module (BCM), a critical component in modern vehicles responsible for managing various electronic systems, including lighting, security features, and interior comfort controls. When the BCM detects an issue, it triggers the check engine light or the warning light specific to the system affected. Common in vehicles like the 2015-2018 Honda Civic, this code can arise from issues such as short circuits, electrical faults, or programming errors. If not addressed, the problems can lead to malfunctioning lights, power windows, or even security system failures. In practical terms, a vehicle with a B107E code might exhibit symptoms like the inability to lock or unlock doors remotely, erratic dashboard lights, or non-functioning accessories. Ignoring this code can lead to further complications, including additional electrical issues and potentially leaving the vehicle inoperable. Therefore, understanding and addressing the B107E code is crucial for maintaining your vehicle's electronic systems and overall reliability.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B107E is present:
- Check engine light remains illuminated or flashes intermittently, indicating a serious issue with the vehicle's electrical systems.
- Power windows and locks may operate inconsistently, causing frustration and possible security concerns.
- Dashboard lights may flicker or fail to illuminate, making it difficult to monitor vehicle status.
- Malfunctioning climate control systems, which may lead to uncomfortable driving conditions.
- Issues with the vehicle's alarm system, such as false alarms or failure to activate.
Possible Causes
Most common causes of B107E (ordered by frequency):
- The most common cause of the B107E code is a short circuit within the wiring harness, with a likelihood of about 50%. This can happen due to wear and tear or exposure to moisture.
- Another frequent cause is a faulty Body Control Module itself, which can occur due to manufacturing defects or electrical surges.
- Corrosion at the BCM connectors is also a known issue, which can be prevented by regular inspection and maintenance to keep connectors clean and dry.
- Less common but serious causes include faulty sensors linked to the BCM, which can disrupt multiple systems and require comprehensive diagnostics.
- Rarely, a software glitch may lead to the B107E code; in this case, reprogramming the BCM may resolve the issue.
