Common Questions
What does B067B mean and how does it affect my car?
The B067B code means there's an issue with the driver's door lock switch or its connection to the BCM. This can lead to problems with locking and unlocking your doors, potentially leaving your vehicle vulnerable. If ignored, it might cause additional electronic failures that could affect other systems in your vehicle.
What are the most common causes of B067B and how much does it cost to fix?
Common causes include a faulty door lock switch or damaged wiring. Repair costs vary, with switch replacement typically costing between $100 to $200, while BCM issues can range from $300 to $800.
Can I drive my car with B067B or should I stop immediately?
While you can typically drive your vehicle with the B067B code, it's advisable to address the issue promptly. Ignoring it could lead to more significant electrical problems or security issues.
How can I diagnose B067B myself using GeekOBD APP?
Using the GeekOBD APP, you can perform a scan to check for the B067B code and any related codes. The app allows you to view freeze frame data and monitor live data from the BCM, helping you identify the issue more accurately.
What vehicles are most commonly affected by B067B?
The B067B code is frequently reported in the 2015-2018 Honda Accord, as well as other models with similar BCM configurations, including certain Toyota and Nissan models from that timeframe.
How can I prevent B067B from happening again?
Regularly inspect your vehicle’s wiring and connectors, especially in the door area. Keep moisture away from electrical components and consider using protective sprays to prevent corrosion.
What is B067B?
The B067B diagnostic trouble code indicates an issue related to the vehicle's body control module (BCM), specifically involving the driver's door lock switch. This code is often triggered when the BCM detects an abnormal voltage signal from the switch or if it fails to communicate properly with other systems, such as the power door locks. For drivers of vehicles like the 2015-2018 Honda Accord, experiencing this code typically results in malfunctioning door locks or alarm systems. If left unaddressed, it can lead to further electrical problems, impacting other components like the vehicle's security system. The BCM plays a critical role in managing various electrical functions, and any issues can create a cascade of problems. Therefore, understanding the B067B code is crucial for maintaining your vehicle's overall health and ensuring all electronic systems work as intended.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B067B is present:
- The check engine light or a warning light on the dashboard stays illuminated, indicating a fault detected by the BCM.
- Door locks may fail to operate properly, such as not locking or unlocking with the switch or remote.
- Power windows or other electrical components related to the driver's door may malfunction, impacting driver convenience.
- Possible intermittent issues with the vehicle's alarm system, leading to false alarms or failure to activate.
- Increased battery drain if the BCM continuously tries to communicate with a faulty switch.
Possible Causes
Most common causes of B067B (ordered by frequency):
- The most common cause of the B067B code is a faulty door lock switch, which is responsible for sending signals to the BCM. This accounts for about 60% of cases.
- Another potential cause could be damaged wiring or connectors between the door lock switch and the BCM, which can create signal interruptions.
- Moisture intrusion or corrosion in the door's electrical components can lead to short circuits, causing the BCM to throw the B067B code. Regular inspections can help prevent this.
- Less common causes include a malfunctioning BCM itself, which may require reprogramming or replacement depending on the severity of the issue.
- In rare cases, other electronic components in the door may fail, which can lead to miscommunication with the BCM and trigger the B067B code.
