What is B07FB?

DTC B07FB is a diagnostic trouble code that indicates a fault within the vehicle's body control module (BCM) or its communication with other modules. This code is often seen in various Ford models, particularly the 2016-2020 Ford Explorer, where it can signify issues related to electrical systems, such as lighting or door locks. When this code is triggered, it may affect vehicle functions such as keyless entry or power windows, leading to potential safety concerns. The BCM is responsible for managing many electronic features in your vehicle, and when it malfunctions, it can lead to erratic behavior in these systems. For example, you might experience intermittent failures of your power locks or dashboard lights that flicker or don’t work at all. Ignoring this code can lead to further electrical issues down the line, so it's essential to address it promptly. If you're experiencing symptoms associated with DTC B07FB, it’s advisable to get a professional diagnosis to pinpoint the exact cause of the issue and ensure your vehicle operates safely and reliably.

Possible Causes

Most common causes of B07FB (ordered by frequency):

  1. The most common cause of DTC B07FB is a faulty body control module (BCM), which accounts for about 60% of cases. This often results from wear and tear or exposure to moisture.
  2. Another common cause is damaged wiring or loose connections, typically around the BCM, which can lead to poor communication between modules.
  3. Corrosion in connector pins can also trigger this code, often due to moisture exposure, making it essential to inspect connectors during diagnostics.
  4. A less common but serious cause could be a software glitch in the BCM, requiring an update or reprogramming to resolve.
  5. Rarely, issues with the vehicle's electrical system, such as a failing battery or alternator, can indirectly cause DTC B07FB to trigger.
