Common causes include a faulty BCM, wiring issues, and poor ground connections. Repair costs can range from $100 for wiring repairs to $600 for BCM replacement, depending on the severity of the issue and the specific repairs needed.
Can I drive my car with B0C87 or should I stop immediately?
While you may be able to drive your vehicle with the B0C87 code, it is not advisable to ignore it. Continuing to drive could lead to more significant electrical failures. It's best to have the vehicle inspected as soon as possible.
How can I diagnose B0C87 myself using GeekOBD APP?
Using the GeekOBD APP, you can perform an OBD2 scan to retrieve the B0C87 code and any related codes. The app also allows you to view freeze frame data that can help you understand the context of the fault, which is critical for accurate diagnosis.
What vehicles are most commonly affected by B0C87?
The B0C87 code is often found in vehicles like the 2015-2020 Ford F-150 and other Ford models. These vehicles may have specific recalls or TSBs related to BCM issues, which can be beneficial to check with your dealer.
How can I prevent B0C87 from happening again?
Regular maintenance, such as checking electrical connections and ensuring proper grounding, can help prevent the recurrence of B0C87. Additionally, avoiding aftermarket electrical additions that can interfere with the BCM is advisable.
What is B0C87?
The diagnostic trouble code (DTC) B0C87 indicates an issue with the vehicle's Body Control Module (BCM), specifically relating to a malfunction in the communication between the BCM and other modules. This code can manifest in various ways, including unusual behavior of electrical systems such as power windows, lighting, and the vehicle's keyless entry system. When the BCM fails to receive or send proper signals, it can lead to erratic functioning of these components, often leaving drivers confused about their vehicle's reliability. For vehicle owners, this can mean intermittent problems that may seem trivial at first but could escalate into more significant issues if not addressed. In models like the Ford F-150 (2015-2020), this code has been reported frequently, often in conjunction with symptoms like flickering lights or unresponsive electronic features. Ignoring this code can lead to more costly repairs down the line, as underlying issues may worsen. It’s crucial to address the B0C87 code promptly to ensure the safety and functionality of your vehicle’s electrical systems.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0C87 is present:
- Check engine light remains illuminated, indicating persistent communication issues with the BCM.
- Power windows and locks may work intermittently, causing frustration for users who rely on these features for convenience.
- Interior lights flicker or do not function correctly, which can be distracting and unsafe during nighttime driving.
- Keyless entry system fails to function, preventing convenient access to the vehicle.
- Vehicle may experience stalling or failure to start due to compromised electronic systems.
Possible Causes
Most common causes of B0C87 (ordered by frequency):
- {'cause': 'Faulty Body Control Module (BCM)', 'likelihood': '40%', 'details': 'The BCM may fail due to age or manufacturing defects, leading to miscommunication with other vehicle systems.'}
- {'cause': 'Wiring Issues', 'details': 'Damaged or corroded wiring harnesses can disrupt signals between the BCM and other components, resulting in error codes like B0C87.'}
- {'cause': 'Poor Ground Connections', 'details': 'Insufficient grounding can lead to erratic module behavior. Regular checks can help prevent this issue.'}
- {'cause': 'Software Glitches', 'details': 'Occasionally, software updates may be needed to address communication bugs within the BCM, especially in newer vehicles.'}
- {'cause': 'External Electrical Interference', 'details': 'Aftermarket electronic accessories can interfere with BCM signals, leading to unexpected B0C87 codes.'}
