Can I drive my car with B0FAE or should I stop immediately?
While it may be safe to drive, it's advisable to address the B0FAE code soon to prevent potential battery drain and further electrical issues. Ignoring it could lead to inconvenient situations with your liftgate.
How can I diagnose B0FAE myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for diagnostic trouble codes and view freeze frame data to understand when the error occurred. This will help you identify if the liftgate switch or wiring may be the source of the problem.
What vehicles are most commonly affected by B0FAE?
The B0FAE code is often seen in 2016-2021 Ford Explorer and F-150 models. These vehicles have been reported to have liftgate system issues, so owners should be mindful of this code.
How can I prevent B0FAE from happening again?
Regularly inspect the liftgate switch and wiring for wear, especially in harsh weather conditions. Keeping the electrical connections clean and ensuring the battery is in good condition can help prevent B0FAE from recurring.
What is B0FAE?
The diagnostic trouble code (DTC) B0FAE indicates an issue with the vehicle's body control module (BCM) related to the power liftgate system. This code typically signifies that the BCM has detected a fault in communication with the liftgate's motor or switches. In practical terms, this may lead to the power liftgate failing to open or close, which can be frustrating for drivers who rely on this feature for convenience. If your vehicle is equipped with a power liftgate, you may experience symptoms such as the liftgate not responding to the remote key fob or the liftgate switch inside the vehicle. The issue can stem from various causes, including wiring problems, faulty switches, or even a malfunctioning BCM itself. Drivers in vehicles like the 2017 Ford Explorer or 2018 F-150 should be particularly vigilant, as these models have been noted for this issue. Ignoring a B0FAE code could lead to further complications, including potential drain on the vehicle’s battery due to the liftgate motor attempting to operate without success.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0FAE is present:
- The power liftgate does not respond when using the remote key fob, making it impossible to open or close from a distance.
- The liftgate switch inside the vehicle is unresponsive, preventing manual operation of the liftgate.
- You may notice that the vehicle's battery drains quicker than usual, indicating potential electrical issues.
- The liftgate may partially open or close, suggesting intermittent communication with the BCM.
- Warning lights may appear on the dashboard, indicating a broader issue with the vehicle's electrical system.
Possible Causes
Most common causes of B0FAE (ordered by frequency):
- A faulty power liftgate switch is the most common cause, occurring in about 40% of cases due to wear and tear or moisture intrusion.
- Wiring issues, such as frayed wires or poor connections, can lead to communication failures with the BCM, accounting for around 30% of problems.
- A malfunctioning BCM itself may cause the B0FAE code, which requires a specialized diagnostic to confirm, and is less common but serious.
- In rare instances, issues with the vehicle's battery or charging system can affect the liftgate's function, making up about 10% of cases.
- Corrosion at connection points, particularly in regions with harsh weather, can create intermittent connectivity problems, contributing to about 5% of reported cases.
