What vehicles are most commonly affected by B0F97?
The B0F97 code is frequently reported in models like the Ford F-150 (2015-2020), Ford Explorer (2016-2020), and some Lincoln models. Be sure to check for any recalls or technical service bulletins (TSBs) related to your vehicle.
How can I prevent B0F97 from happening again?
Regular maintenance, including checking electrical connections and keeping the BCM updated, can help prevent the B0F97 code from recurring. Additionally, avoiding water damage to electrical components is essential.
What is B0F97?
The B0F97 diagnostic trouble code (DTC) is primarily associated with issues in the Body Control Module (BCM) or the vehicle's electrical systems. This code indicates that there is a problem with the communication between the BCM and other modules within the vehicle. As a result, various systems such as lighting, door locks, and alarms may not function as intended. For example, you may notice that your interior lights stay on when the doors are closed, or the keyless entry system may fail to respond. The B0F97 code can lead to further complications if not addressed, as it can disrupt the overall functionality of your vehicle’s electrical systems. It’s essential to understand that while this code may not immediately affect the engine's performance, it can lead to safety concerns, such as malfunctioning lights or alarms that could put you at risk on the road. If you own a 2015-2020 Ford F-150 or other models with similar systems, being aware of this code can save you from costly repairs in the long run. Regular diagnostics and maintenance checks can help mitigate these issues, ensuring that your vehicle remains safe and operational.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0F97 is present:
- The check engine light remains illuminated, indicating a fault in the vehicle's electronic systems.
- Interior lights may not turn off when the doors are closed, leading to battery drain.
- Keyless entry system may become unresponsive, making it difficult to lock or unlock doors.
- Power windows may operate intermittently, causing inconvenience during operation.
