What are the most common causes of B0E79 and how much does it cost to fix?
Common causes include a faulty BCM (50% likelihood) or corroded wiring (30%). Repair costs can range from $100 to $600 depending on the issue, with wiring repairs being less expensive than BCM replacement.
Can I drive my car with B0E79 or should I stop immediately?
It is advisable to avoid driving until the issue is diagnosed and repaired, as it could lead to more significant electrical problems and safety concerns.
How can I diagnose B0E79 myself using GeekOBD APP?
Use the GeekOBD APP to scan for trouble codes and view live data from your vehicle's sensors. Look for any abnormal readings that may indicate wiring issues or BCM faults.
What vehicles are most commonly affected by B0E79?
B0E79 is frequently seen in 2015-2018 Honda Accord models, but can also affect other vehicles with advanced electrical systems. Check for any recalls related to your specific model.
How can I prevent B0E79 from happening again?
Regular maintenance, including inspecting electrical connections and ensuring moisture doesn't enter the vehicle, can help prevent this code from reappearing.
What is B0E79?
DTC B0E79 is a diagnostic trouble code that indicates a problem with the vehicle's body control module (BCM) or related systems. This code is particularly common in vehicles like the 2015-2018 Honda Accord and other models equipped with advanced body control features. When this code is triggered, it often signifies that the BCM has detected an irregularity, such as improper signals from various sensors that control lighting, windows, or locks. In practical terms, this means that certain electrical components in your vehicle may not function as intended. For instance, you might experience issues with power windows not responding, interior lights failing to turn on or off, or even problems with the vehicle's alarm system. Ignoring this code can lead to more severe electrical issues over time, as the underlying problem may escalate. Therefore, it is essential to address the B0E79 code promptly. A thorough diagnosis using an OBD2 scanner, such as the GeekOBD APP, is recommended to pinpoint the exact issue and ensure your vehicle operates smoothly.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0E79 is present:
- Check engine light stays on constantly, indicating the BCM has recognized a fault.
- Power windows may fail to operate properly, leading to frustration when trying to adjust them.
- Interior lights may flicker or not function, causing inconvenience especially at night.
- Keyless entry system might become unresponsive, affecting your ability to lock or unlock doors.
- Dashboard warning lights may illuminate unexpectedly, further complicating the electrical system's functionality.
Possible Causes
Most common causes of B0E79 (ordered by frequency):
- Faulty body control module (BCM) - 50% likelihood. This component can fail due to electrical shorts or manufacturing defects.
- Corroded wiring or connectors - 30%. This often results from exposure to moisture, causing communication issues between BCM and sensors.
- Faulty sensors (e.g., door or lighting sensors) - 15%. These components can degrade over time, sending incorrect signals to the BCM.
- Software glitches - 4%. Occasionally, BCM software may require updates to function correctly.
- Battery issues - 1%. Weak batteries can cause voltage irregularities affecting the BCM's performance.
